Question

Factorise the following:

(4x−15)2−(x+12)2 with steps

Answer 1

6x - 54

Explanation:

(4x − 15)2 − (x+12)2,

8x - 30 - 2x - 24,

6x - 54

Answer 2

8x-30-2x+24

Explanation:

First, factor the first parentheses. Distribute 2 to 4x, and then to 15, giving you 8x-30.

Next, factor the 2nd parentheses. Distribute 2 to x, and then to 12, giving you 2x+24.

Now, write the new equation: 8x-30-2x+24
