Learning Objective
I can use the quadratic formula to find the solutions of quadratic equations.
- 1
The quadratic formula can be used to solve equations in the form 0 = ax² + bx + c, where a, b, and c are coefficients.
- 2
The quadratic formula states that x = -b ± √(b² - 4ac) / 2a, giving two possible solutions for x.
- 3
In the example, a = -7, b = 2, and c = 9, which are substituted into the quadratic formula to find the solutions for q.
