The GCF is 4.
If you mean: 12a+14a-4 then it can be simplified to 26a-4
12a + 4 - 10a = 2a + 4 or 2*(a + 2)
4(x2 + 4)
2(3n+4)
4(x+6)
4
(a + 6)(a + 4)
It multiplies out as: 12a-12+2 = 12a-10
To factorise the expression (4a + 12b), first identify the greatest common factor (GCF) of the coefficients. The GCF of 4 and 12 is 4. You can then factor out 4 from the expression: [ 4(a + 3b). ] Thus, the factorised form is (4(a + 3b)).
2x2 - 9x + 4 = (2x - 1)(x - 4)
X2 + 4xx(x + 4)=======
