Quadratic Formula Practice

In the equation
y = x² +5x +7, match each leading coefficient with its correct letter 

• a=0, b=5, c=7
• a=1, b=5, c=7
• a=7, b=5, c=1

Identify the 'b' value: y = 16x² -8x -24

• 16
• -8
• 8
• -24

Identify the 'c' value: y = 16x² -8x -24

• 16
• -8
• 8
• -24

Solve using the quadratic formula.

2x² - 9x - 35 = 0

• x = 3.5, x = -6

• x = -2.5, x =5

• x = -0.5, x =6

• x = -2.5, x = 7
