Question

If (x – a) is a factor of x3 + ax2 - 2x + a + 4, then what will be the value of ‘a’ ? PLZ ANSWER FAST

Answer 1

Answer:

If (x – a) is a factor of x3 + ax2 - 2x + a + 4, then it will be divided by x3 + ax2 - 2x + a + 4.

Step-by-step explanation:

by remainder theorem : x-a=0

x=a

putting value in = P(X) = x3 + ax2 - 2x + a + 4

P(a) = (a)³+a(a)2-2(a)+a+4

= a³ + 2a² - 3a+4

Now ,finding value of A ≈ a³+ 2a² -3a+4

a³+ 2a² -3a+4 = 0
