Question 466627: Hello! I have a hard time with fractions. Here is my problem, and I wish to know if I worked it out correctly.
(3/4x + 1/2)^2
= (3/4x + 1/2) (3/4x + 1/2)
= 3/4x * 3/4x = 9/16x^2 --> 3/4x * 1/2 (((2/4 * 3/4x)) = 6/16x
= 1/2 * 1/2 = 1/4
= 9/16x^2 + 6/16x + 6/16x + 1/4
= 9/16x^2 + 12/16x + 1/4
I want to know if I worked this problem out correctly.
