Answer:
16x^2 + 16x + 4
Step-by-step explanation:
Apply the so-called FOIL method of multiplying products of binomials: F stands for 'first terms,' which are 4x and 4x; O stands for "outer terms," which are 4x and 2; I stands for 'inner terms,' which are 2 and 4x; and L stands for "last terms," which are 2 and 2.
To evaluate (4x+2) (4x+2), (4x+2) (4x+2) = 16x^2 + 8x + 8x + 4
This simplifies to
16x^2 + 16x + 4
