Yes it is. The thing that makes it a quadratic equation is that "x squared" in there.

It is a quadratic equation.

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 + 1)(2x + 1) or (2x + 1)2 so x = -0.5

(2x-4)(x-1) = 0

y=x2+2x+1 -b -2 2a= 2= -1 = axis of symmetry is negative one.

3x2 + 2x - 8 = 0 is a quadratic equation.

The [ 2x + 1 ] represents a function of 'y' .

3x(2x + 1)

x = the square root of -2

They intersect at the point of: (-3/2, 11/4)

Yes.

(-3, -5)

If: y = 4x2-2x-1 and y = -2x2+3x+5 Then the length of the line works out as: 65/18 or 3.6111 ... recurring decimal 1

You need to clarify the function AND provide an interval.

2x + 52 = 7 2x + 25 = 7 2x = 7 - 25 2x = -18 x = -18/2 x = -9

It can not be factored because its discriminant is less than zero

(x - 3)(x + 5)

3(2x - 1)(x - 2)

-x2+2x

If: x2+2x-3 = 0 Then: x = 1 or x = -3

If 2x + 3y = 4, y= (4 - 2x)/3. In function notation, f(x) = (4 - 2x)/3.

2x squared plus 2x plus xy plus y or 2x(x+1) + y(x+1) or (x+1)(2x+y)
