Quadratic Formula

What is the first step in using the quadratic formula?

• Calculate the discriminant

• Substitute the values into the formula

• Set the equation equal to zero

• Identify the coefficients a, b, and c

What do you need to calculate after substituting values into the quadratic formula?

• The roots of the equation

• The vertex of the parabola

• The discriminant

• The maximum value of the quadratic function

What happens if the discriminant is negative?

• The equation has two identical real solutions

• The equation has no real solutions

• The equation has one real solution

• The equation has two distinct real solutions

How can you simplify the square root of 12 in the context of solving quadratic equations?

• 2 radical 3

• 3 radical 4

• 4 radical 3

• 12 radical 1

What should you do if you encounter an irrational solution while solving a quadratic equation?

• Convert the solution to a rational number

• Simplify the radical if possible

• Ignore the solution as it is not valid

• Estimate the solution using a calculator
