Answer:
first we have divide
8x/2x their power going to sub 3-9
4xpower-6
we have to keep than 1/4power sign going to plus
1/4 power 6
72 = 1/2 (16x) because the area of a triangle is 1/2 (bh) and the height is x and the base is 16 and the area = 72 so solve for x to get base.
(a+b)(a-b)=a^2 - b^2
so
<span>(4x-7)(4x+7) = 16x^2 - 49
answer
</span>16x^2 - 49
