Difference of Squares –
When you subtract two terms that are perfect squares.
Ex. x2 – 9
Perfect Square Trinomial –
Whenever you multiply a binomial by itself twice, the resulting trinomial is called a perfect square trinomial
Ex. x2 + -10x + 25
Quadratic Formula –

Quadratic Equation –
An equation that can be written in standard form as ax2 + bx + c = 0
Vertical Motion Model – h= -16t2 + vt + s
Vertical Stretch –
When a parabola becomes more narrow
Vertical Shrink –
When a parabola becomes wider.
Reflection –
When a parabola flips over the x-axis.

Translation –
When a parabola moves up, down, left, or right.
Parent Quadratic Function –
The equation that you compare other equations to. It is y=x2
Discriminate –
The discriminant is calculated by calculating what is under the radical in the quadratic equation. This tells you how many solution you will have.
Domain –
The domain is your x value or input.
Range –
The range is your y value or the output.
Zero of a Function –
To find the zero of a function you input 0 for y and then solve. This find your x value/s.
Vertex Form –
A way to rewrite a quadratic function that makes it very easy to graph form. y= a(x-h)2 + k
Vertex is (h,k)
Axis of symmetry is x=h

Axis of Symmetry –
The x value that creates the reflection of the parabola.
Binomial –
A polynomial with two terms.
Ex. Ax+b
Completing the Square –
A method used to find the value of x in a quadratic equation.
Degree of a monomial –
The sum of all of the exponents of variables.
Degree of a polynomial –
The largest exponent in a polynomial.
Factor by grouping –
You must multiply a and c then find the factors of that sum that equal the middle term
Leading coefficient –
The leading coefficient is the number in front of the variable.
Maximum Value –
The maximum value of a
