Question

The value of a and b when f(x) = 2x³ + ax² -11 + b is exactly divisible by (x-2)(x+3):​

Answer 1

Answer:

$\huge\bf\underline\red{AnSweR:}$

Since (x - 2) and (x + 3) are the Factors of f(x)...

$f(z) = 0 \: and \: f( - 3) = 0$

$4a + b = 6$

$9a + b = 21$

Solving (i) & (ii)

$a = 3 \: and \: b = - 6$
