Properties of addition
Properties of addition
What you'll learn
- Identify the coefficients a, b, and c in a quadratic equation written in standard form (ax² + bx + c = 0) with 100% accuracy.
- Apply the quadratic formula (x = [-b ± √(b² - 4ac)] / 2a) to solve quadratic equations with real number solutions, achieving at least 80% accuracy on a problem set.
- Solve quadratic equations using the quadratic formula, including those with irrational and complex solutions, and express the solutions in simplest form with at least 75% accuracy on an assessment.
- Explain the relationship between the discriminant (b² - 4ac) and the nature of the roots (real, distinct, real and equal, or complex) of a quadratic equation with clear and concise justification in written form.
