(x + 2y) ^2
(x + 2y) (x + 2y)
x^2 + 2xy + 2xy + 4y^2
= x^2 + 4xy + 4y^2
Change mixed fraction to improper fraction and also the second fraction has to be reciprocal
Ex- 3/8= 8/3
So now the problem is
13/8*8/3= 13/3 (because you cross divide) Now, turn into fraction
Divide
13 divided by 3= 4 1/3
So your final answer is 4 1/3
Your answer is 6
6 * 3 = 18
