Factor 5a-15 Factor out the 5; 5(a-3)
5a
It is: 5(a+b)
5a2-15 = 5 (a2-3) = 5 (a-sqrt(3))(a+sqrt(3)) as a2-b2=(a-b)(a+b)
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.
(2a-3)(a-1)
The other factor is 1.
3a4 - 2a2 + 5a - 10 - 2a4 + 4a2 + 5a - 2 = a4 + 2a2 + 10a - 12 = a4 + (2a - 2)(a + 6)
5a3-45a=-2a2+18 5a(a2-9)=-2(a2-9) 5a=-2 a=-2/5
Factor 5a-15 Factor out the 5; 5(a-3)
Multiply the first and last coefficients.2*3=6What two factors give you six but when combined give you -5-2 and -3Therefore2x-3)(x-1) will be the factored model.
5a4 + 3a3 + 2a2
5a-20=
5a
a(2a + 1)
I'll assume the missing signs are pluses. 7a^2 - 12a + 14
5a(a(a-5)+3)
