If the discriminant equals zero the equation has solution(s).?
If the discriminant of a quadratic equation equals zero, it indicates that the equation has exactly one real solution, also known as a repeated or double root. This occurs because the quadratic touches the x-axis at a single point, rather than crossing it. Mathematically, this means that the two roots are the same, resulting in one unique solution for the equation.
What is true of an equation if its discriminant is zero?
it has one real solution
If the discriminant equals zero the equation has solutions?
Yes and they will be of equal value
What is the discriminant of 8x2-2x plus 8 equals 0?
(-2)2-4*8*8 = -252 The discriminant is less than zero so there's no solution to the quadratic equation.
What is a discriminant and how does help to solve equations?
In the quadratic formula, the discriminant is b2-4ac. If the discriminant is positive, the equation has two real solutions. If it equals zero, the equation has one real solution. If the discriminant is negative, it has two imaginary solutions. This is because you find the square root of the discriminant and add or subtract it from -b and divide the sum or difference by 2a. If the square root is of a positive number, then you get two different solutions, one from adding the discriminant to -b and one from subtracting the discriminant from -b. If the square root is of zero, then it equals zero, and the solution is -b/2a. If the square root is of a negative number, then you have two imaginary solutions because you can't take the square root of a negative number and get a real number. One solution is from subtracting the discriminant from -b and dividing by 2a, and the other is from adding it to -b and dividing by 2a. The parabola on the left has a positive discriminant. The parabola in the middle has a discriminant of zero. The parabola on the right has a negative discriminant.
If the discriminant of a quadratic equation equals zero what is true of the equation?
It has one real solution.
If the discriminant of an equation is zero then?
The term "discriminant" is usually used for quadratic equations. If the discriminant is zero, then the equation has exactly one solution.
When will an equation have no solution?
If the discriminant of a quadratic equation is less than zero then it has no solutions.
What is true of an equation if its discriminant is zero?
it has one real solution
If the discriminant equals zero the equation has solutions?
Yes and they will be of equal value
What is a discriminant in a quadratic equation?
General form of a quadratic equation is: ax2+b+c = 0 The discriminant is: b2-4ac If the discriminant equals zero then there are two equal roots If the discriminant is greater than zero then there are two different roots If the discriminant is less than zero then there are no real roots
What is the discriminant of 8x2-2x plus 8 equals 0?
(-2)2-4*8*8 = -252 The discriminant is less than zero so there's no solution to the quadratic equation.
What is the discriminant of this equation eight x square plus five x plus six equals zero?
The discriminant is -167.
What does the discriminant tell you?
The discriminant tells you how many solutions there are to an equation The discriminant is b2-4ac For example, two solutions for a equation would mean the discriminant is positive. If it had 1 solution would mean the discriminant is zero If it had no solutions would mean that the discriminant is negative

What can the discriminant tell you about a quadratic equation?
It can tell you three things about the quadratic equation:- 1. That the equation has 2 equal roots when the discriminant is equal to zero. 2. That the equation has 2 distinctive roots when the discriminant is greater than zero. £. That the equation has no real roots when the discriminant is less than zero.
