Solving Quadratic Functions

What are the x-intercept/s of the function? 

• (3,0)
• (-3,0)
• (9,0) & (-9,0)
• (-3, 0) & (3, 0)

Find the zeros of the quadratic equation y=4(x+9)²-36

• x=-9+√6 & x=-9-√6
• x=3 & x=-3
• x=-6 & x=-12
• so solution

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5
• Add 6 to both sides and multiply both sides by 5
• Subtract 6 from both sides then multiply both sides by 5
• Subtract 6 from both sides then divide both sides by 5

4x + 10 = -26

• 4
• -4
• -9
• 9

Solve
4m² - 100 = 0

• m=25, -25
• m=96
• m=5, -5
• m=-96

What is the vertex of the parabola?

y = 3(x + 5)² - 4

• (5, -4)
• (-5, -4)
• (-15, -4)
• (15, -4)

Use the square root property to solve the Quadratic Equation.
