What form does the equation take when setting up a quadratic equation for a rectangle's area?

• w(2w - 1) = 28

• w + 2w - 1 = 28

• w^2 + w - 28 = 0

• 2w^2 - w = 28

Which method can be used to solve the quadratic equation 2w^2 - w - 28 = 0?

• Substitution

• Graphing

• Quadratic formula

• Elimination
