factoring quadratics

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

Does the quadratic have a maximum or minimum vertex, and does the parabola open up or down?

• max/ opens down

• min/ opens up

• max/ opens up

• min/ opens down

The graph of a quadratic function is called a

• Parabola
• Vertex
• Axis of Symmetry 
• Vertex Form

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

• 2 and -2

• 4 and -4

• 16 and -16

• 8 and -8

Solve by taking square roots:
5m² + 1 = 6

• m = 0
• m = 1 or -1
• m = √7
• m = 7/5 m = -7/5

What is standard form of a quadratic Equation?

• Ax² + Bx + C = 0

• Ax² + B + Cx = 0

Factor:

x² + 11x + 24

• (x + 6)(x + 4)

• (x + 12)(x + 2)

• (x - 8)(x - 3)

• (x + 8)(x + 3)
