## Study Notes

• Factoring quadratics is the process of expressing a quadratic expression as a product of two binomials.

• Find x-intercepts of quadratic graphs

• Factoring Out the Greatest Common Factor (GCF)
• Factor out the GCF from each term
• Leave the remaining terms in factored form
• Factoring by Grouping
• Group terms with common factors
• Factor out the GCF from each group
• Factoring Using the AC Method
• Multiply the coefficients of the x^2 and constant terms (AC)
• Find two factors of AC that add up to the coefficient of the x term
• Rewrite the quadratic using these factors

• Simple Quadratic: x^2 + 5x + 6 = (x + 3)(x + 2)
• Quadratic with Negative Coefficients: x^2 - 7x - 12 = (x - 3)(x - 4)
• Quadratic with Non-Integer Coefficients: 2x^2 + 5x + 3 = (2x + 1)(x + 3)

Tips and Tricks

• Look for common factors before attempting to factor
• Use the AC method when the coefficient of the x term is negative
• Check your factors by multiplying them together to ensure they equal the original quadratic expression
