Here the student found the x values for x² - 8x + 15 = 99

• x = -6 and x = 14

• ...

Answer explanation

One variable equations must be set equal to y or not have an equals sign to be graphed in the State Test version.

NOTE: Get the equation on one side and then exclude the equals sign or just put =y

Use the graph to determine the solutions.

• -1 and -3
• 1 and -3
• 1 and 3
• -1 and 3
