Answer:
13
Explanation:
Step 1 to find gcf of 16x^2 -16+3 is factor out the equation = (4x)^2 -13 = (4x+13)(4x-13) So we factor to show one - and one + and then step 2 we then divide 4/4 -13/4 and 4/4 13/4 and cancel out 4/4 and see what we are left with = x>+ - 13/4 = 3 1/4 we can now find gcf by working out 16x^2 = 16(3 1/4)^2 = 16(10.5625) = 169 and the gcf of 169 and +- 13 = 13
