2a^2b^3(4a^2+3ab^2-ab)=?
<span>
is what I presume you actually meant. </span>
<span>
Pull out the common factors of (4a^2+3ab^2-ab) and you will get </span>
<span>
a(4a+3b^2 -b) </span>
Substitute this back into the original equation and you get
<span>
2a^2b^3[a(4a+3b^2-b)] = </span>
2a^3b^3(4a+3b^2-b) =
<span>2a^3b^3(4a-b+3b^2)

corrected question:
A rectangle and a square have the same perimeter. One side-length of the rectangle is 25% longer than the other. What is the ratio between the areas of the rectangle and the square?
Answer:
ratio of area of recatngle to square= 0.9879
Step-by-step explanation:
perimeter of rectangle = 2(L+B)
perimeter of a square =
L=B+0.25B
L=1.25B
= 2(L+B)
= 2(1.25B+B)
= 2(2.25B)
= 4.5B
B= 4/4.5
B= 0.889
..........equ1
area of square =
area of rectangle = L*B
=1.25B*B=
ratio of area of recatngle to square =
referring to equ 1
ratio of area of recatngle to square = 
=
ratio of area of recatngle to square= 0.9879
