This is a multiplying binomials problem. Multiply the first term in the first binomial by both terms in the second binomial: \(4 x^2+4x\)
Then multiply the second term in the first binomial by each term in the second binomial: 2x+2
Adding them all together you get:
\(4 x^2+4x+2x+2\)
\(4 x^2+6x+2\).
