Answer» <P>*********************************** Factor Theorem : Let p(x) be a polynomial of degree ONE or more than 1 and a is a real number . Then, i ) x - a , will be a factor of p(x), if p(a) = 0 , Conversely , ii ) If x - a is a factor of p(x) , then p(a) = 0. *************************************, Here , F(x) = x³ + 3x² + 3X + 1 , G(x) = x + 1 , g(x) = 0 => x + 1 = 0 => x = -1 , Therefore , ZERO of g(x) is -1. Now , F(-1) = (-1)³ + 3(-1)² + 3(-1) + 1 = -1 + 3 - 3 + 1 = -4 + 4 = 0 Therefore , By Factor theorem , g(x) is a factor of F(x). •••••• |
