(4, -2)
7x-4=x+2 7x=x+2+4 7x=x+6 7x-x=6 6x=6 X=1
It is: x-1+4+7x-3 = 8x simplified
7(x + 4)
x^2 +7x+12 = (x+3)(x+4) when factored
=3x * * * * * The correct answer is: x2 + 7x + 12 = (x + 3)(x + 4).
7x + 16 = 3x + 4 4x = -12 x = -3
x2-7x+12 (x-3)(x-4)
Do you mean x2+7x+12? If so then it is: (x+3)(x+4)
(7x - 4)(7x + 4).
9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6
11x+9=7x+21 11x-7x=4 4x+9=21 21-9=12 4x=12 12 divided by 4= 3 x=3

many solutions
x2-7x+12 = 0 (x-3)(x-4) = 0x=3,4
It is (x+3)(x+4) when factored
