Quadratic Formula

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

• Zero

• Negative

If the discriminant (under the square root) is zero, how many solutions does the graph have?

• 2

• 1

• 0

• a = 2 , b = 3, c = -5

• a = 2, b = -3, c = 5

• a = 2, b = -3, c = -5

• a = -2, b = 3, c = 5
