Question

Simplify (x - 3)(x^2+ 7x - 8). (1 point)

Answer 1

x^3 + 7x^2 -8x -3x^2 -21x +24

x^3 + 4x^2 -29x +24

Answer 2

For this case we must simplify the following expression:

`(x-3) (x ^ 2 + 7x-8)`

We must apply distributive property:

`x * x ^ 2 + x * 7x-8 * x-3 * x ^ 2-3 * 7x + 3 * 8 =\\x ^ 3 + 7x ^ 2-8x-3x ^ 2-21x + 24 =`

Adding similar terms we have:

`x ^ 3 + 4x ^ 2-29x + 24`

Answer:

The simplified expression is:

`x ^ 3 + 4x ^ 2-29x + 24`
