Question

Multiply (6x^3 - 5x^2 + 4x) by (x^2 + 7x - 1)​

Answer 1

$( 6{x}^{3} - 5 {x}^{2} + 4x )\: ( {x}^{2} + 7x - 1) \\ \\ 6 {x}^{3} ( {x}^{2} + 7x - 1) - 5 {x}^{2} ( {x}^{2} + 7x - 1) \\ + 4x( {x}^{2} + 7x - 1) \\ \\ {6x}^{5} + 42 {x}^{4} - 6 {x}^{3} - 5 {x}^{4} - 35 {x}^{3} + 5 {x}^{2} \\ + 4 {x}^{3} + 28 {x}^{2} - 4x \\ \\ 6 {x}^{5} + 37 {x}^{4} - 37 {x}^{3} + 33 {x}^{2} - 4x$
