Answer:
81y^4 - 16x^2, difference of squares.
Step-by-step explanation:
So we need to expand the following product:
(9y2-4x)(9y2+4x) = 9y2*9y2 + 4x*9y2 - 4x*9y2 -4x*4x = 81y^4 - 16x^2
And this type of product is the difference of squares.

-(m-8)= -8m+29
-1(m-8)=-8m+29-------------Note: there is always an invisible 1 in front
-m+8=-8m+29---------------Subtract both sides by -8
-m=-8m+21-------------------Add both sides by +m
0=-7m+21---------------------Add +7m to both sides
7m=21 -------------------------Divide both sides by 7
m=3
