The solution is
p = +2 or p = -15 .
Here is how to get it.
p2 + 13p - 30 = (p - 2) ((p + 15)
So, if p2 + 13p - 30 = 0 then (p - 2) ((p + 15) = 0.
The product of two numbers equals 0 if and only one of the factors is zero.
so solve the linear equations:
p -2 = 0 and p + 15 = 0 and get
p = +2 or p = -15 .
n = 3/2, n = 2
a = 0. That is because a = 0 implies that there is no quadratic term and so the equation is not a quadratic!There may be some who make claims depending on the value of the discriminant (which is b2-4ac). That is true only for elementary mathematics. In more advanced mathematics (complex analysis), the quadratic equation can be used in all cases except when a = 0: the value of the discriminant is irrelevant.a = 0.

The answer is 3. :p
It depends on the level of your mathematical knowledge. One way is to differentiate the quadratic equation and find the value of x for which the derivative is 0. The advantage of this method is that it works for turning points of polynomials of all degrees. The disadvantage is that you need to know differentiation. For a quadratic, an alternative, and simpler way is to write the equation in the form: y = ax2 + bx + c Then the x value of the vertex is -b/2a
It is an equation and the value of b is 3
It means you are required to "solve" a quadratic equation by factorising the quadratic equation into two binomial expressions. Solving means to find the value(s) of the variable for which the expression equals zero.
x = 9/2 or x = -2 Solved by using the quadratic equation formula.
Using the quadratic equation formula the value of x is -8 or 5
-0.82 , -4.82
Using the discriminant formula for a quadratic equation k has a value of 8/25 or maybe 0.
D
dunctions are not set equal to a value
it is 1
Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.
It is the value of the discriminant of a quadratic equation.
You substitute the value of the variable into the quadratic equation and evaluate the expression.
