Question

_please help_____________​

Answer 1

Answer:

the value of x is 2

Step-by-step explanation:

Since a+x is a factor of the polynomial

a+x =0

a = -x

substitute the value in the polynomial

2a² + 2xa + 5a + 10 = 0

2(-x)² + 2x(-x) + 5(-x) + 10 = 0

2x² - 2x² -5x + 10 = 0

collect like terms

-5x = -10

divide both sides by -5

x = -10/-5

x = 2
