Question

Find the product of the given polynomials. (5 x +8 -6x) (4+ 2x 87)

a. -2x2+19x -24
b-2x2 -24x +19
c- 2x2 +19x +24
d- 2x2 +13x -24

Answer 1

`- 2x^2 +19x -24`

Explanation:

Given

`(5x + 8 - 6x)(4 + 2x - 7)`

Required

Evaluate

We have:

`(5x + 8 - 6x)(4 + 2x - 7)`

Collect like terms

`(5x - 6x+ 8 )(4 - 7+ 2x )`

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

Expand

`3x - 2x^2 -24 + 16x`

Rewrite as:

`- 2x^2 + 3x+ 16x -24`

`- 2x^2 +19x -24`
