Question

multiply (x square -3) (2x-7xsquar +4) and write the degree of the product
​

Answer 1

Answer:

$( {x}^{2} - 3)(2x - 7 {x}^{2} + 4) \\ \\ = 2 {x}^{3} - 7 {x}^{4} + 4 {x}^{2} - 6x + 21 {x}^{2} - 12 \\ \\ = - 7 {x}^{4} + 2 {x}^{3} + 4 {x}^{2} + 21 {x}^{2} - 6x - 12 \\ \\ = - 7 {x}^{4} + 2 {x}^{3} + 25 {x}^{2} - 6x - 12 \\ \\ so \: the \: required \: degree \: is \\ \\ 4$
