5a2 - 20ab - 25b2
= 5(a2 - 4ab - 5b2)
= 5(a2 - 4ba - 5b2) since -5b*b = -5b2 and -5b + b = -4b, then
= 5(a - 5b)(a + b)

Can 30 plus ab plus 6b plus 5a be factored?
30 + ab + 6b + 5a = 5(a+6) + b(a+6) = (b+5)(a+6)
Factor 25a squared minus 20ab plus 4b squared?
This is not a difficult factorisation, as it is merely a normal factorisation with "a" stuck on the end of each number. 25a(2) - 20ab + 4b(2) (2b-5a)(2b-5a) This is: 2bx2b=4b(2) 2bx-5a=-10ab (twice) -5ax-5a=25a
