Question

Simplify (x-2)(x+6) using grouping and write the result expression in standard form

Answer 1

x^2 + 4x - 12.

Explanation:

(x - 2)(x + 6)

= x(x + 6) - 2(x + 6)

= x^2 + 6x - 2x - 12

= x^2 + 4x - 12.

Answer 2

(x + 2)(x + 6)

= x(x + 6) + 2(x + 6)

= x ∙ x + 6x + 2x + 2 ∙ 6(Distribute the terms.)

= x2 + 6x + 2x + 12

= x2 + 8x + 12(Combine like terms.)

Step-by-step explanation: don't put this all!!! just put the answer. This is plato answer!!!! I copied it so don't put it all, just put x2 + 8x + 12
