Solving Quadratic Equations with Formulas

• If b^2 - 4ac > 0, there are two real solutions.
• To use the quadratic formula, substitute the values from the standard form into the formula.
• The quadratic formula is used to find the roots (x-intercepts) of a quadratic equation.
• If b^2 - 4ac < 0, there are no real solutions.
• If b^2 - 4ac = 0, there is one real solution (repeated).
• The quadratic formula can be used to find the roots of any quadratic equation.
• The discriminant is the expression inside the square root sign when using the quadratic formula to find x-intercepts.
• The discriminant is calculated by subtracting ac from b^2.
• When solving quadratic equations by factoring, look for factors that multiply to ac.
• Factoring can be helpful in finding the zeros of a polynomial function.
• When using the quadratic formula, make sure that all terms have like bases and coefficients.
• When solving quadratic equations using factoring or completing the square, it's important not to forget any terms when combining like terms.
