Identify Form of Quadratic Trinomial: Identify the form of the quadratic trinomial, which is g2−2g−3.
Find Multiplying and Adding Numbers: Look for two numbers that multiply to −3 (the constant term) and add up to −2 (the coefficient of the linear term).
Use Numbers for Factored Form: The numbers −3 and 1 work because −3×1=−3 and −3+1=−2.
Check Factoring by Expanding: Write the factored form using these two numbers: (g−3)(g+1).
Simplify Expanded Form: Check the factoring by expanding (g−3)(g+1) to see if it gives the original expression.
Simplify Expanded Form: Check the factoring by expanding (g−3)(g+1) to see if it gives the original expression.Expanding gives: g2+g−3g−3, which simplifies to g2−2g−3.
