Checkpoint: Solving Quadratics

Front

Which equation matches standard form of a quadratic? Options: ax + by = c, y = a(x - h)² + k, y = ax² + bx + c, y = mx + b

Back

y = ax² + bx + c

Front

What is another word for zeros?

Back

roots

Front

Find the zeros.

Back

0 and 4

Front

What are the roots of the function?

Back

x = -4, 1

Front

What is the discriminant?

Back
