Question

Find the product of the following polynomials.
a. f(X) = (x2 - 3x + 2)and
g(X) =(4x2 + 6x - 7)​

Answer 1

Step-by-step explanation:

$= 4 {x}^{2} ( {x}^{2} - 3x + 2) + 6x( {x}^{2} - 3x + 2) + 2( {x}^{2} - 3x + 2) \\ = 4 {x}^{4} - 12 {x}^{3} + 8 {x}^{2} + 6 {x}^{3} - 18 {x}^{2} + 12x - 7 {x}^{2} + 21x - 14 \\ = 4 {x}^{4} - 6 {x}^{3} - 17 {x}^{2} + 33x - 14$
