2) then you just add the fractions
B.(a-b)(a+b)
Because the radius of the numerical number would be hostile once intercepting the equivalent factor would be a^2(b-b^2)
Completing the square will always work for any quadratic, because you can always manipulate any quadratic by following completing the square.
42.38 is the answer i think.
