the dimensions are: )
step-by-step explanation:
we want to find the dimensions of a rectangular box with volume of
=50b^3+75b^2-2b-3)
we factor to obtain;
=(2b+3)(25b^2-1))
we rewrite the rightmost factor to obtain;
=(2b+)^2-1^2))
recall that:
(a-b))
we apply difference of two squares formula to obtain;
=(2b+3)(5b-1)(5b+1)
hence the dimensions are
