Quadratics Practice

Solve by factoring.

x² + 15x + 44 = 0

• {-8, 2}

• {-7, 5}

• {-11, -4}

• {-11}

The solutions of the quadratic equation

x²+12x+35=0 are (hint: find the zeros) FACTOR

• x = -5 or x = -7

• x = 5 or x = 7

• x = -35 or x = -1

• x = -9 or x = -4

The solutions of the quadratic equation

x²+2x-15=0 are (hint: find the zeros) FACTOR

• x = 3 or x = 5

• x = 5 or x = -3

• x = -5 or x = 3

• x = -3 or x = -5

Solve by factoring.

b² + 2b - 24 = 0 (hint: find the zeros) FACTOR!

• x = 6 or x = -4

• x = -6 or x = -4

• x = 6 or x = 4

• x = -6 or x = 4

What do the "Zeros" represent on a quadratic equation graph?

• x-intercepts

• y-intercepts

• vertex

• focus

The graph of a quadratic function is called a

• Parabola
• Vertex
• Axis of Symmetry 
• Vertex Form

Solve x²− 4 = 0 (solve using square roots)
