Question

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

Answer 1

(x+8)

Explanation:

Answer 2

x2 + 8x + 12

Explanation:

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

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

= x2 + 6x + 2 (x + 6)

= x2 + 6x + 2x + 2 * 6

= x2 +6x + 2x + 12

= x2 + 8x + 12
