Question

if a is equal to 2 x square - 3 x + 3 and 13 is equal to x square minus x minus 3 then the value of a into B is

Answer 1

$a = 2 {x}^{2} - 3x + 3 \\ b = {x}^{2} - x - 3 \\ a \times b = (2 {x}^{2} - 3x + 3)( {x}^{2} - x - 3) \\ = 2 {x}^{4} - 2 {x}^{3} - 6 {x}^{2} - 3 {x}^{3} + 3 {x}^{2} + 9x + 3 {x}^{2} - 3x - 9 \\ = 2 {x}^{4} - 5 {x}^{3} + 6x - 9$
