Question

Find the values of a and b, if (x + 1) and (x + 2) are factors of x3 + 3x2 – 2ax + b.​

Answer 1

Step-by-step explanation:

Let f(x) = x3 + 3x2 − 2αx + β be the given polynomial from factor theorem, if (x+1) and (x+2) are factors of f(x) then f(-1) = 0 and f(-2) = 0 Read more on Sarthaks.com - https://www.sarthaks.com/107034/find-and-if-x-1-and-x-2-are-factors-of-x-3-3x-2-2x
