Select the quadratic that has roots x=8 and x=-5

Quadratic equation:

Step-by-step explanation:

We are given two roots of the quadratic equation and we need to find the quadratic equation.

If roots are a and b then equation

Roots are x=8 and x=-5

Sum of roots  = 8 + (- 5) = 3

Product of roots = 8 x -5 = -40

Substitute the value into formula

Quadratic equation:

In factor form:

Hence, The equation is  

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
