Find the equation for the roots 7 and - 2.

(x - 7) (x + 2)

Step-by-step explanation:

Create equation-

(x - 7) (x + 2)

Multiply-

Take the term multiply it with each variable or number and add with the product of the second term multiplied with the variable and number, as so:

x * x = x^2

x * 2 = 2x

-7 * x = - 7x

-7 * 2 = - 14

x^2 + 2x - 7x - 14

Combine like terms

x^2 - 5x - 14

To confirm

-14

-7 and 2 go into - 14 and add to - 5
