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