A86 · HSA.REI.D.11

Solving Quadratics by Graphing

I can solve a quadratic equation from its graph and say how many real solutions it has.

See the lesson

A87 · HSA.REI.B.4b

Solving by Factoring and the Zero Product Property

I can solve a quadratic equation by getting 0 on one side, factoring and setting each factor to 0.

See the lesson

A88 · HSA.REI.B.4b

Solving Quadratics by Square Roots

I can solve x² = k and (x − h)² = k by taking both square roots.

See the lesson

A89 · HSA.REI.B.4a

Solving Quadratics by Completing the Square

I can solve a quadratic equation by completing the square on both sides.

See the lesson

A90 · HSA.REI.B.4b

The Quadratic Formula

I can solve a quadratic equation with the quadratic formula.

See the lesson

A91 · HSA.REI.B.4b

The Discriminant and Number of Solutions

I can use the discriminant to say how many real solutions a quadratic equation has.

See the lesson

A92 · HSA.REI.C.7

Linear-Quadratic Systems

I can solve a system of a line and a parabola and give every solution as a point.
