Review Solving Quadratics

Solve using intercept form (Lesson 9.2 - Part B). What are the x-intercepts of the parabola

y = ¼(x + 2)(x - 6)?

• -2 and 6

• 2 and -6

• -2

• ¼ and -2 and 6

Solve using intercept form (Lesson 9.2 - Part B). What are the x-intercepts of the parabola?

y = -3(x + 5)(x - 9)

• -5 and 9

• 5 and -9

• 5 and 9

• -3 and 5 and -9

Solve by using square roots (Lesson 9.3).

(x+6)²=49

• x=7,12

• x=±7

• x=1,-13

• x=43,-55

Solve by using square roots (Lesson 9.3).

x² = 49

• -7

• 7

• 49

• ±7

Solve by using the Quadratic Formula (Lesson 9.5).

2x² + 2x - 12?

• -2, 3

• 2, 3

• 2, -3

• -2, -3

Solve by using the Quadratic Formula (Lesson 9.5).

x² + 3 = -4x

• x = -1, -3

• No Real Solution

• x = 1.19883425, -0.002234

• x = 8, -3

Name this formula:

• Pythagorean Theorem

• Clark's Formula

• Quadratic Formula

• Maxwell's Equations for Electromagnetism

What is the standard form for a Quadratic?

• ax²+ bx = - c
• x = -b ± √(b²-4ac) / 2a
• ax² + bx + c
• y = mx + b

Solve the equation using the zero product property.
(x- 9)(x + 3) = 0

• x = 3 or x = 9
• x = 3 or x = -9
• x + -3 or x = 9
• x = -3 or x = -9

Solve the equation using the zero product property.
3x ( 2x - 4) = 0

• x = -1/3 or x = -2
• x = 0 or x = 2
• x = 0 or x = -2
• x = -1/3 or x = 2
