The GCF is 3x.
The GCF of 30 x^2 and 45x is 15x. The GCF of 30 and 45 is 15, and the GCF of x squared and x is x.
Factorising 15x-27xy gives 3x (5 - 9y).Factorising is to express a number or expression as a product of factors.When factorising always look for common factors. To factorise (15x-27xy) look for the highest factor between the two terms (3x). 15x - 27y = 3x (5 - 9y)
15x - 3xy = 3x(5 - y) 20 - 4y = 4(5 - y) 15x - 3xy + 20 - 4y = (3x + 4)(5 - y)
Since 3x is a factor of 3x^2, it is automatically the GCF.
3x. 15x - 9x = 6x 9x - 6x = 3x 6x - 3x = 3x 3x - 3x = 0
The GCF is 3x.
-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2
The GCF is 15x.
If x>1 then the gcf is 15x. If x<1 then the gcf is 15.
GCD(15x, 24x) = 3x
-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2
The GCF is 3.

The GCF of 30 x^2 and 45x is 15x. The GCF of 30 and 45 is 15, and the GCF of x squared and x is x.
15x minus 8=minus 180 3x+8=24
