Identify Coefficients: Step Title: Identify the CoefficientsConcise Step Description: Identify the coefficients of the quadratic equation, which are the numbers in front of the variables. In this case, the coefficients are 100, −140, and 49.Step Calculation: Coefficients are 100, −140, 49Step Output: Coefficients: 100, −140, 49
Rearrange Standard Form: Step Title: Rearrange in Standard FormConcise Step Description: Rearrange the quadratic equation in standard form, which is ax2+bx+c.Step Calculation: The standard form is 49x2−140x+100.Step Output: Standard Form: 49x2−140x+100
Factor Greatest Common Factor: Step Title: Factor the Greatest Common Factor (GCF) Concise Step Description: Factor out the greatest common factor from the coefficients. Step Calculation: The GCF of 49, −140, and 100 is 1. Step Output: Since the GCF is 1, we cannot factor anything out.
Find Factors: Step Title: Find the FactorsConcise Step Description: Find two numbers that multiply to the product of the first and last coefficients 49×100 and add to the middle coefficient −140.Step Calculation: Factors of 4900 that add up to −140 are −70 and −70.Step Output: Factors: −70, −70
Write 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.Step Calculation: The factored form is (7x−10)2, since (7x−10)(7x−10) gives 49x2−70x−70x+100.Step Output: Factored Form: (7x−10)2
