Question

$4 {x}^{2} (x - 1) - 6 {x}^{3} (x {}^{2} - 1)$
​

Answer 1

Answer:

${4x}^{2} (x - 1) - 6 {x}^{3} ( {x}^{2} - 1) \\ \\ {4x}^{3 } - {4x}^{2} - {6x}^{5} - {6x}^{3} \\ \\ - 4 {x}^{2} - 2 {x}^{3} - 6 {x}^{5}$

Take minus comman

$- (4 {x}^{2} + {2x}^{3} + 6 {x}^{5} )$

Answer 2

4x^2(x-1)-6x^3(x^2-1)

=> 4x^3-4x^2-6x^5+6x^3

=>10x^3-4x^2-6x^5

=>-4x^2-6x^5+10x^3

=>-2x^2-3x^5+5x^3
