2x + 7 = 1 Therefore, 2x = -6 x = -6/2 x = -3
-2y square exp power -2x-1
3x-2 = 2x+3 3x-2x = 3+2 x = 5
x2 + 2x - 15 = 0(x + 5) (x - 3) = 0x = -5x = +3

(x - 3)(x + 5)
2x + 52 = 7 2x + 25 = 7 2x = 7 - 25 2x = -18 x = -18/2 x = -9
x2 - 2x + 55 = 90x2 - 2x - 35 = 0(x+5)(x-7) = 0x = -5, 7

Yes it is. The thing that makes it a quadratic equation is that "x squared" in there.
2x+a=p 2x=p-a x=.5p-.5a
y= -2x
Add the x's squared together to get 2x^2+x. You cannot add anymore so the answer is 2x^2+x
The solution comprises every point on a parabola which is symmetric about the y axis and has its apex at (0,1).
It cannot be solved because the discriminant of the quadratic equation is less than zero
It is a quadratic equation.
