Guided Notes
3 key concepts
- 1
When a function intersects the x-axis, f(x) = 0, so to solve the equation, set the quadratic equation equal to 0 and factor.
- 2
To factor a quadratic in the form x² + bx + c, find two numbers that add to b and multiply to c.
- 3
If (x + a)(x + b) = 0, then either x + a = 0 or x + b = 0, so x = -a or x = -b.
