Answer:
a = 2
Step-by-step explanation:
Equation : 2x² + 2ax + 5x + 10
If (x + a) is a factor, then by substituting x = -a into the equation, the equation will return zero.
Substitute x = -a
2x² + 2ax + 5x + 10
= 2(-a)² + 2a (-a) + 5(-a) + 10
= 2a² - 2a² - 5a + 10
= -5a + 10
The equation will return zero
-5a + 10 = 0
-5a = -10
a = 2
Answer: a = 2
