Tutorial

1) Write title at the top of the page

2) Draw Cornell line

3) Write all questions & answers

4) Write all examples

**DISCRIMINANT**: The part of the quadratic formula under the square root (b^{2} - 4ac). Tells the number of roots.

**FACTORED FORM**: Any quadratic equation in the form y = (x - a)(x - b)

**FACTORING**: To break up terms into smaller like terms (for this unit, to go from standard to factored form)

**LINE OF SYMMETRY**: The vertical line through the vertex, splits parabola into two mirror-image pieces

**QUADRATIC EQUATION**: A polynomial with a highest term of x^{2}

**QUADRATIC FORMULA**: Formula solves for the roots of any standard form quadratic equation

**PARABOLA**: A graph of a quadratic equation

**PERFECT SQUARE**: A number that is square of another number (Ex: 9 is a perfect square, 9 = 3*3)

**POLYNOMIAL**: Any finite set of terms with positive exponents being added, subtracted, or multiplied

**ROOTS**/**ZEROS**: The point or points where a parabola intersects the x-axis.

**STANDARD FORM**: Any quadratic equation in the form: y = ax^{2} + bx + c

**VERTEX**: The point on the graph where the parabola changes direction from positive to negative or negative to positive
