Let's solve the world's math problems!
now the problem is $(4x-2)(4x-2)$
now the problem is $(4x-2)(4x-2)$
Step 1: use the foil method...multiply these two to get $16x^2$
Step 2: then these two to get -8x
Step 3: then these two to get -8x
Step 4: then these two to get 4
Step 5: put all of this together to get $16x^2-8x-8x+4$
Step 6: the result is $16x^2-16x+4$
Step 7: 4(4x^2 - 4x +1)
