Evelyn, Aiden, and Abigail are trying to solve a real-world problem using a quadratic equation. They came up with the equation
4x² – 8x = 3. Can you help them determine the values of
a, b, and c in their equation?

• 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 appropriate method of solving can we used in the equations that are written in the form x² = c?

• factoring

• quadratic formula

• extracting square roots

• completing the square
