Find the Factors: Step Title: Find the FactorsConcise Step Description: Find two numbers that multiply to the product of the first coefficient 3 and the last term −35, which is −105, and add to the middle coefficient −16.Step Calculation: Factors of −105 that add up to −16 are −21 and 5.Step Output: Factors: −21, 5
Write the Factored Form: Step Title: Write the Factored FormConcise Step Description: Write the factored form of the quadratic equation using the factors found in the previous step, and then factor by grouping.Step Calculation: 1. Split the middle term using the factors −21 and 5: 3x2−21x+5x−352. Factor by grouping:(3x2−21x)+(5x−35)3x(x−7)+5(x−7)3. Factor out the common binomial factor (x−7):(3x+5)(x−7)Step Output: Factored Form: (3x+5)(x−7)
