The discriminant is the part of the quadratic b2 equation under the radical, 4ac. We use the discriminant to determine the number of real solutions of ax2 + bx + c = 0 as such :

In this lesson students begin by establishing the difference between an expression and an equation. Students then investigate expressions and equations to develop what it means to …

it is possible to calculate the coefficients of the quadratic equation by substituting in the x and y values of the 3 points to create a system of 3 equations in 3 unknowns:

Combine similar terms on each side of the equation. Add or subtract terms on both sides of the equation to get the unknowns on one side and the number on the other side.

An equation in the form y = ax 2 + bx + c ( a ≠ 0 ), is referred to as “Quadratic” and its graph is a parabola. Here are examples of the graphs of two quadratic equations along with the tables …
