Quadratic- Factors and Zeroes

Write a quadratic equation given the x intercepts and one other point.

Step 1: Write the factors.

The intercepts of this function are (6, 0) and (8, 0). Write the factors.

Which equations matches the graph above?

Which of the following is the correct equation for the given graph?

Write a quadratic equation for the graph.

• x² + 4x - 3

• x² - 2x - 3

• x² + 2x - 3

• x² - 4x - 3

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.

x² + 44 = -15x

• {-8, 2}

• {-7, 5}

• {-11, -4}

• {-11}
