Solving Quadratic Equations & such

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

Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3

• a = 4, b = -8, c = 3
• a = 4, b =-8, c =-3
• a = 4, b = 8, c = 3
• a = 4, b = 8, c = -3

What is "b" in the equation 3x² −7 = 0 ?

• 3

• 7

• 0

• 10

What is the "c" value in the equation

4x² = 76 ?

• 4

• 76

• 0

• -76

• A
• B
• C
• D

The first step in solving quadratic equations is to . . .

• factor

• write the equation in standard form

• use quadratic formula

• complete the square

Solve the equation by factoring.

• x = {3,8}

• x = {-3,8}

• x = {3,-8}

• x = {-3,-8}
