Question

02.08) simplify (10x2− 8x − 1) (4x2− 8x − 5). (1 point) 14x2− 16x 6 14x2 16x 6 14x2− 16x − 6 14x2 16x − 6

Answer 1

Option C is correct.

Simplified expression of
`(10x^2 -8x -1) + (4x^2-8x -5)` is,
`14x^2 -16x -6`

Explanation:

To simplify the expression:
`(10x^2 -8x -1) + (4x^2-8x -5)`

First remove the parenthesis, we have;

`10x^2 -8x -1 + 4x^2-8x -5`

Like terms defines as the terms whose variables are the same.

Combine like terms;

`(10x^2+4x^2) + (-8x -8x) + (-1-5)`

Simplify:

`14x^2 -16x -6`

therefore, the simplified given expression is.,
`14x^2 -16x -6`

Answer 2

(10x^2 - 8x - 1) + (4x^2 - 8x - 5) = 10x^2 - 8x - 1 + 4x^2 - 8x - 5 = 14x^2 - 16x - 6
