Question

If x+1 is the factor of x^3+ax+2a-2. What is the value of a

Answer 1

✒ If x + 1 should be the factor of the polynomial p(x) must be equal to 0.

So,

• x + 1 = 0
• x = 0 - 1
• x = - 1

Substitute the value of x in p(x)....

➡ (-1)³ +a(-1) + 2a - 2 = 0

➡ -1 - a + 2a - 2 = 0

➡ a - 3 = 0

➡ a = 0 + 3

➡ a = 3

Therefore, the value of a is “ 3 ”
