Solving Quadratics

What should you do first in solving this equation?
x² + 6x - 13 = 3

• Get factored form
• Write down: a=1, b=6, c=-13
• Make it equal 0 by subtracting 3 on each side
• Type it all in a calculator.

Convert x²-6x+9 to factored form and identify the solution.

• (x-3)(x-3); x=3
• (x+3)(x+3); x=-3
• (x+4)(x+2); x=-4, -2
• Not factorable

Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3

• a = 4, b = -8, c = 3
• a = 4, b =-8, c =-3
• a = 4, b = 8, c = 3
• a = 4, b = 8, c = -3

What is another word for zeros?

• y-intercepts
• roots
• vertex
• axis of symmetry

Solve:
X² - 3 =6X + 10

• X = 7, -1
• X = -7, 1
• X = -7, -1
• No Solution

What  are the solutions of this graph?

• -2 and 3
• -1/2 and -6
• -2 and -6
• 3 and -6

How many zeros does this parabola have? 

• 3
• 2
• 0
• 1

Find the zeros.

• 0 and 4
• 0 and -4
• 0
• -4

If the graph of a quadratic does not intercept the x-axis at any point, then it has:

• 1 Real Solution
• 2 Real Solutions
• Half a Solution
• No Real Solution

What is another word that describes the zeroes of a quadratic function?
