Yes it is. The thing that makes it a quadratic equation is that "x squared" in there.
It is a quadratic equation.
y=x2+2x+1 -b -2 2a= 2= -1 = axis of symmetry is negative one.
(2x-4)(x-1) = 0

It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.
(2x-4)(x-1) = 0
(2x + 1)(2x + 1) or (2x + 1)2 so x = -0.5
The [ 2x + 1 ] represents a function of 'y' .
3x(2x + 1)
Yes.
3x2 + 2x - 8 = 0 is a quadratic equation.
