Identify Coefficients: Step Title: Identify the CoefficientsReasoning: Identify the coefficients of the quadratic equation, which are 1 for y2, 2 for y, and −15 as the constant.Calculation: Coefficients are 1, 2, −15
Find Factors: Step Title: Find the FactorsReasoning: Find two numbers that multiply to −15 (the constant) and add to 2 (the coefficient of the middle term).Calculation: Factors of −15 that add up to 2 are 5 and −3.
Write Factored Form: Step Title: Write the Factored FormReasoning: Use the factors found to write the quadratic in its factored form.Calculation: The factored form is (y+5)(y−3).
