Full solution

Q. Solve the equation: 2x2+5x7=02x^{2}+5x-7=0
  1. Identify Coefficients: Step Title: Identify the Coefficients\newlineConcise Step Description: Identify the coefficients of the quadratic equation, which are the numbers in front of the variables. In this case, the coefficients are 22, 55, and 7-7.\newlineStep Calculation: Coefficients are 22, 55, 7-7\newlineStep Output: Coefficients: 22, 55, 7-7
  2. Find Factors: Step Title: Find the Factors\newlineConcise Step Description: Find two numbers that multiply to the product of the leading coefficient 22 and the constant term 7-7, which is 14-14, and add to the middle coefficient 55.\newlineStep Calculation: Factors of 14-14 that add up to 55 are 77 and 2-2.\newlineStep Output: Factors: 77, 2-2
  3. Rewrite Middle Term: Step Title: Rewrite the Middle Term\newlineConcise Step Description: Rewrite the middle term using the factors found in the previous step.\newlineStep Calculation: The quadratic equation can be rewritten as 2x2+7x2x7=02x^2 + 7x - 2x - 7 = 0.\newlineStep Output: Rewritten Equation: 2x2+7x2x7=02x^2 + 7x - 2x - 7 = 0
  4. Factor by Grouping: Step Title: Factor by Grouping\newlineConcise Step Description: Group the terms into two pairs and factor out the common factors from each pair.\newlineStep Calculation: Factor out xx from the first pair and 1-1 from the second pair to get x(2x+7)1(2x+7)=0x(2x + 7) - 1(2x + 7) = 0.\newlineStep Output: Factored by Grouping: x(2x+7)1(2x+7)=0x(2x + 7) - 1(2x + 7) = 0
  5. Factor Out Binomial: Step Title: Factor Out the Common Binomial\newlineConcise Step Description: Factor out the common binomial factor from the two groups.\newlineStep Calculation: The common binomial factor is (2x+7)(2x + 7), so the factored form is (x1)(2x+7)=0(x - 1)(2x + 7) = 0.\newlineStep Output: Factored Form: (x1)(2x+7)=0(x - 1)(2x + 7) = 0
