Question

Find the product. -2 xa (-4 xb - 2 x 3 + 5 x )

Answer 1

`8x^(a+b)+4x^(3+a)-10x^(a+1)`

Explanation:

We need to find the product of:
`-2x^(a)(-4x^(b)-2x^(3)+5x)`

We have that:

`-2x^(a)(-4x^(b)-2x^(3)+5x)` =
`8x^(a+b)+4x^(3+a)-10x^(a+1)`

We can't simplify more the expression, therefore, the solution is:

`8x^(a+b)+4x^(3+a)-10x^(a+1)`.
