Question

Expand and simplify( x+4)(x-3)​

Answer 1

Step-by-step explanation:

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

Answer 2

Answer:

The answer is x² + x - 12.

Step-by-step 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.
