(x2 + 4x - 6)(2x3 - 6x)

Multiply the each term

2x5 + 8x4 -12x3 - 6x3 -24x2 + 36x

Simplify

2x5 + 8x4 - 18x3 -24x2 + 36x.

The algebraic expression is (x2 + 4x - 6)(2x3 - 6x)

(x2 + 4x - 6)(2x3 - 6x) = x2 (2x3) + x2 (- 6x)+ 4x (2x3) + 4x(- 6x) - 6(2x3) - 6(- 6x)

Prouduct of powers property image

= 2x2+3 - 6x2+1 + 8x1+3 - 24x1+1 - 12x3 + 36x

= 2x5 - 6x3 + 8x4 - 24x2 - 12x3 + 36x

= 2x5 + 8x4 - 6x3  - 12x3 - 24x2 + 36x

(x2 + 4x - 6)(2x3 - 6x) = 2x5 + 8x4 - 18x3 - 24x2 + 36x.
