Solving Quadratics

Solve
4m² - 100 = 0

• m=25, -25

• m=96

• m=5, -5

• m=-96

Solve
a² + 2a - 24 = 0

• a = -6, 4
• a = 6, -4
• a = 12, -2
• a = 8, -3

Solve      3x² - 192 = 0

• -32 or 32
• No Solution
• -8 or 8
• -64 or 64

What are the zeros?

• x= 0 and x= -4
• x= 0 and x= 4
• y= 0
• x= 2

True or false:
The solutions, roots, x-intercepts, and zeros of a quadratic equation are all the same thing.

• True
• False, because the solution and root are the same but the x-intercept and zero are different
• False, because the x-intercept and root are the same but the zero and solution are different
• False, they are all different

Find the zeros of the equation: 
(x+10)(x-2) = 0

• 10 and 2
• -2 and 10
• -10 and 2
• -2 and -10

Solve
2x² + 17x + 21 = 0

• x= ^-21/₂, -17
• x= ²/₃, 16
• x=-7, ^-3/₂
• x=15, -³/₇

x² + 44 = -15x

• {-8, 2}

• {-7, 5}

• {-11, -4}

• {-11}

Solve using Zero-Product Property
(x-11)(5x+1) = 0

• x = 11 or x = -1/5
• x = -11 or x = -1/5
• x = 11 or x = 1/5
• x = -11 or x = 1/5

What are the solutions/zeros/x-intercepts/roots?
