Quadratic Formula Practice

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

• x = {-6.37, -0.63}

• x = {-7.53, 0.53}

• x = {0.63, 6.37}

• x = {-8.48, 1.48}

• No Solution

• x = {-1.13, 0.53}

• x = {-2.65, 5.65}

• x = {-1.74, 1.14}

• x = {0.76, 5.24}

• x = {0.67, 5.42}

• x = {-1.47, 7.47}

• No Solution

• x = {-0.45, 4.45}

• x = {-0.90, 8.90}

• x = {-4.45, 0.45}

• x = { -2.24, 6.24}

• No Solution

• x = {-1.91, -0.59}

• x = {-0.64, 3.14}

• x = {-1.27, 6.27}

Solve using the quadratic formula.
2x² - 9x - 35 = 0

• x = {-6, 7/2}

• x = {-5/2, 5}

• x = {-3/7, 6}

• x = {-5/2, 7}

2x²-x -3=0

• x = {-3/2, 1}

• x = {-1, 3/2}

• x = {-3/2, -1}

• x = {1, 3/2}

Solve using the quadratic formula:

4x² + 4x + 1 = 0

• x = -½

• x = -2

• x = 0

• x = ½

Solve 2x² + 7x - 15 = 0

• x = {-3/2, 5}

• No Solution

• x = {-5, 3/2}

• x = {0.7, 5}
