Answer:

x - 3

Step-by-step explanation:

sum = 7

Product = -30

Factors = 10 , -3

x² + 7x - 30 = x² + 10x - 3x - 3 *10

                  = x(x + 10) - 3(x + 10)

                  =(x + 10)(x -3)

[tex]\frac{x^{2} + 7x - 30}{x + 10}= \frac{(x+10)(x-3)}{(x + 10)}\\\\[/tex]

             = x - 3
