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)
The square root of 25a squared is 5a. The square root of 16 is 4.So the answer is (5a+4)(5a-4)
a2 + -5a2 - a2 - a = a2 - 5a2 - a2 - a = a2 - 6a2 - a = -5a2 - a
30 + ab + 6b + 5a = 5(a+6) + b(a+6) = (b+5)(a+6)
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
The GCF is 5a.

a2-5a-14 = (a-7)(a+2) when factored
It simplifies to 5a+4 !
Well, honey, 5a squared is just 5 times a squared. It's as simple as that. So if you're looking for the value of 5a squared, just make sure you don't forget to square that 'a' and multiply it by 5. Easy peasy lemon squeezy!
The square root of 25a squared is 5a. The square root of 16 is 4.So the answer is (5a+4)(5a-4)
No
If you mean: 5a2+24a-5 then it is (5a-1)(a+5) when factored
30a2+89a+63 = (5a+9)(6a+7) when factored
The GCF of 35 a^2 and 85ab is 5a. The GCF of 35 and 85 is 5, and the GCF of a squared and ab is a.
a2 + -5a2 - a2 - a = a2 - 5a2 - a2 - a = a2 - 6a2 - a = -5a2 - a

30 + ab + 6b + 5a = 5(a+6) + b(a+6) = (b+5)(a+6)
