Question

Expand and simplify

( x+4)(x-3)​

Answer 1

Explanation:

`(x + 4)(x - 3) \\ {x}^(2) - 3x + 4x - 12 \\ {x}^(2) + x - 12`

Answer 2

The answer is x² + x - 12.

Explanation:

1) Use foil method: (a + b) (c + d) = ac + ad + b + bd.

`{x}^(2) - 3x + 4x - 12`

2) Collect like terms.

`{x}^(2) + ( - 3x + 4x) - 12`

3) Simplify.

`{x}^(2) + x - 12`

hence, the answer is x² + x - 12.
