It simplifies to: 12x+3y
12x2 + 7x + 1 = 12x2 + 3x + 4x + 1 = 3x*(4x + 1) + 1*(4x + 1) = (4x + 1)*(3x + 1)
(5x 2 - 8x + 1) + (2x 2 - 4x - 11)
Solving these simultaneous equations by the elimination method:- x = 1/8 and y = 23/12
Because you are just adding the same variable to itself, the variable does not change. in the same way that 2 + 2 is 4, 2x2 + 2x2 is 4x2.
4x2+12x = 4x(x+3) when factored
8x squared
It can't be factored because its discriminant is less than zero
The factorisation is as follows: 4x² + 12x + 9 = (2x + 3)2.
x - 2
4x(4x^2 + 3x + 1)
The GCF is 4x.
4x + 20
If you mean: 4x squared+12x-40 then it is (x+5)(x-2) after dividing all terms by 4
(2x - 3)(2x - 3)
(2x - 1)(6x + 5)
The answer is (2x^2+3)(4x+1)
