In the absence of a proper statement of the equation I can only guess at answers. How about (2x + 3)(3x - 5) which is the factorisation of 6x2 - x - 15 = 0?
In which case x = -2/3 or 5/3.

What roots of the quadratic equation are equivalent to xx-x-12 equals 0?
-4,3 are the roots of this equation, so for the values for which the sum of roots is 1 & product is -12
What are quadratic equations with real roots?
If the discriminant of the quadratic equation is zero then it will have 2 equal roots. If the discriminant of the quadratic equation is greater than zero then it will have 2 different roots. If the discriminant of the quadratic equation is less than zero then it will have no roots.
What are the zeros or x-interecepts or soultions or roots of the quadratic equation -7x2 - 27x plus 28 equals 0?
Using the quadratic equation formula:- x = -4.706950048 and x = 0.849071913
How do you solve a quadratic equation graphically?
The roots of the quadratic equation are the x-intercepts of the curve.
What are the roots of the quadratic equation x2 - 6x plus 8 equals 0?
x = 2 and x = 4
What are the roots of the quadratic equation below?
That depends on the equation.
What roots of the quadratic equation are equivalent to xx-x-12 equals 0?

What are quadratic equations with real roots?
If the discriminant of the quadratic equation is zero then it will have 2 equal roots. If the discriminant of the quadratic equation is greater than zero then it will have 2 different roots. If the discriminant of the quadratic equation is less than zero then it will have no roots.
Why do you use square roots to solve quadratic equations?
Because it's part of the quadratic equation formula in finding the roots of a quadratic equation.
What are the roots of the quadratic equation x2 plus 14x plus 45 equals 0?
The roots are: x = -5 and x = -9
Can the answer to a quadratic equation be a decimal?
Yes. You can calculate the two roots of a quadratic equation by using the quadratic formula, and because there are square roots on the quadratic formula, and if the radicand is not a perfect square, so the answer to that equation has decimal.
How many roots does a quadratic equation?
2 roots
What are the zeros or x-interecepts or soultions or roots of the quadratic equation -7x2 - 27x plus 28 equals 0?
Using the quadratic equation formula:- x = -4.706950048 and x = 0.849071913
How many roots does a quadratic equation in one variable have?
A quadratic equation has two roots. They may be similar or dissimilar. As the highest power of a quadratic equation is 2 , there are 2 roots. Similarly, in the cubic equation, the highest power is 3, so it has three equal or unequal roots. So the highest power of an equation is the answer to the no of roots of that particular equation.
How do you solve a quadratic equation graphically?
The roots of the quadratic equation are the x-intercepts of the curve.
How do you find the sum of the roots of the equation x2 plus 5x plus 9 equals 0?
This quadratic equation has no real roots because its discriminant is less than zero.
What are the roots of the quadratic equation x2 - 6x plus 8 equals 0?
x = 2 and x = 4
