Question

Expand
(2x + 7)(x - 5)

Answer 1

`2x^(2)`- 3x - 35

Explanation:

(2x + 7)(x - 5) =
`2x^(2)` - 10x + 7x - 35 =
`2x^(2)`- 3x - 35

Answer 2

To expand multiply each tern in one set of parenthesis by each term in the other set:

(2x+7) (x-5)

Set up each multiplication:

2x*x + 2x*-5 + 7*x + 7*-5

Simplify:

2x^2 -10x +7x -35

Combine like terms:

2x^2-3x-35
