Factorise the following:

(4x−15)2−(x+12)2 with steps

8x-30-2x+24

Step-by-step 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

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

6 × 4.3 = 25.8
