Question

(6b+2)^2=?

Answer 1

You can always distribute, Jamal, if formulas elude you...

First of all (6b + 2)^2 means (6b + 2)(6b + 2)

The acronym FOIL stands for First Outer Inner Last; this phrase helps students to keep track of what they're distributing.  

F: 6b • 6b
O: 6b • 2
I:   2• 6b
L:  2 • 2

So we have 36b^2 + 12b + 12b + 4
Now combine like terms to get:  36b^2 + 24b + 4

Answer 2

(a ± b)² = a² ± 2ab + b²

(6b + 2)² = (6b)² + 2 · 6b · 2 + 2² = 36b² + 24b + 4 = 4(9b² + 6b + 1)
