It is an algebraic expression which is equivalent to 7x - 118.

(4, -2)
7x-4=x+2 7x=x+2+4 7x=x+6 7x-x=6 6x=6 X=1
You cannot solve, without equating it to something. As given it is just an expression. However it can be factored. x^(2) + 7x +12 ( x + 3)(x + 4) Factored but NOT solved. However, it we equate to 'zero(0)' then it can be solved. ( x + 3)( x + 4) = 0 X + 3 = 0 x = -3 Similarly x + 4 = 0 x = -4 Are the solutions (solved).
It is: x-1+4+7x-3 = 8x simplified
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)
9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6
(7x - 4)(7x + 4).
11x+9=7x+21 11x-7x=4 4x+9=21 21-9=12 4x=12 12 divided by 4= 3 x=3

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