x^2 + 12x = 5 x^2 + 12x + __ = 5 + __ x^2 + 12x + 36 = 5 + 36 (The 36 I got from taking half of 12 and then squaring that number (which is 6).) (x + 6)^2 = 41 x + 6 = (the square root of 41) x = (the square root of 41) - 6. Hope that helped :)
8x squared
It is x^2 + 12x or x(x + 12).
4x2+12x = 4x(x+3) when factored
2 root 3x

That doesn't factor neatly. Applying the quadratic equation, we find two real solutions: (-2 plus or minus the square root of 5) divided by 3x = 0.07868932583326327x = -1.4120226591665965
Do you mean y2=x2-12x+17 Well you take the square root from both sides to get y by itself.
That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: -6 plus or minus (3 times the square root of 2) x = -1.75735931288 x = -10.24264
12x and then the squared. (the little two)
x2+12x+5 = 3 x2+12x+5-3 = 0 x2+12x+2 = 0
12i where i is the square root of -1
(3x - y+ 2)(3x + y + 2)
