4(x+6)
x2 + 4x = x(x + 4)
(a + 6)(a + 4)
4x+8y=-24
To factorise the expression ( 12x^2 + 4x ), first identify the greatest common factor (GCF) of the terms. The GCF here is ( 4x ). Factor it out to get ( 4x(3x + 1) ). Thus, the expression can be written as ( 4x(3x + 1) ).
Use www.wolframalpha.com Enter factor 4x^2+8x-5 to receive the answer (2x-1)(2x+5)
x2 + 4x = x(x + 4)
It is: 6(4x+3)
X2 + 4xx(x + 4)=======
(4x-3)(x+2)
It is 2(2x+3) when factorised
(a + 6)(a + 4)

12x2 + 7x + 1 = 12x2 + 3x + 4x + 1 = 3x*(4x + 1) + 1*(4x + 1) = (4x + 1)*(3x + 1)
12x2 - 7x + 1 = 12x2 - 4x - 3x + 1 = 4x(3x - 1) - 1(3x - 1) = (3x - 1)(4x - 1)
4x+8y=-24
4x+2y=24 => 2y=24-4x => y=12-2x and the slope is -2
-2x = -4x + 24 -2x + 4x = 24 2x = 24 x = 24/2 x = 12
