If that's +28, the answer is (x - 4)
The GCF is 1.
Do a prime factorization of both... 28 = 2x2x7 60 = 2x2x3x5 Use the common factor only once and the other factors (2x2) is common to both ... use this only once ( 2x2)x7x3x5 = 420
x2 + 15x + 54 = (x + 6)(x + 9) or (x + 9)(x + 6) since 6*9 = 54 and 6 + 9 = 15However, commutativity is implicit in deriving this factorisation so that the two factorisations are the same.or factor by groupingx2 + 15x + 54= x2 + 6x + 9x + 54= (x2 + 6x) + (9x + 54)= x(x + 6) + 9(x + 6)= (x + 6)(x + 9)
The factorisation is as follows: 2x2 + 7x - 9 = (x - 1)(2x + 9).
2(x - 6)(x + 6)
If you mean: 2x2+7x+5 then it is (2x+5)(x+1) when factored
I think you mean 6x2-15x-21 2x2-5x-7 2x2-7x+2x-7 x(2x-7)+1(2x-7) (x+1)(2x-7)
If you mean: 2x2+15x+25 then it is (2x+5)(x+5)
2x2 + 15x + 25 = (2x + 5)(x + 5)
Show the terms as additive here..., 8X2 + 10X3 factor out 2X2 2X2(4 + 5X) ---------------- 2X2 ==== greatest common factor
2x2 (i.e. 4)
Divide all terms by 3:- 2x2+5x-3 = (2x-1)(x+3) when factored
The GDF is 2x2 =4
The GCF of 4 and 12 is 4.
16=2x2x2x220=2x2x5GCF=2x2=4
(2x2 - 1)(2x2 - 1) or (2x2 - 1)2
If you are talking of 20 and 24 then factor both to prime factors. 20=2x2x5 24=2x2x2x3 circle the common ones. 2x2=4 the greatest common factor.
2: 2x2=4 , 4x2=8, 12x2=24
