Question

Find the square.

(2x – 6)2

Answer 1

(2x-6)^(2)

Multiply each term in the first group by each term in the second group using the FOIL method.
4x^(2)-24x+36

Answer 2

4x^2+36-24x

Answer 3

(2x – 6)^2
= (2x – 6)(2x – 6)
= 2x(2x – 6) -6(2x – 6)
= 4x^2 - 12x -12x +36
= 4x^2 -24x +36
Or you can use the identity (\[(a \pm b)^2 = a^2 \pm 2ab +b^2\]
