Q. Find the values of xx.\newline3x216x35 3 x^{2}-16 x-35
  1. Find the Factors: Step Title: Find the Factors\newlineConcise Step Description: Find two numbers that multiply to the product of the first coefficient 33 and the last term 35-35, which is 105-105, and add to the middle coefficient 16-16.\newlineStep Calculation: Factors of 105-105 that add up to 16-16 are 21-21 and 55.\newlineStep Output: Factors: 21-21, 55
  2. Write the Factored Form: Step Title: Write the Factored Form\newlineConcise Step Description: Write the factored form of the quadratic equation using the factors found in the previous step, and then factor by grouping.\newlineStep Calculation: \newline11. Split the middle term using the factors 21-21 and 55: 3x221x+5x353x^2 - 21x + 5x - 35\newline22. Factor by grouping:\newline (3x221x)+(5x35)(3x^2 - 21x) + (5x - 35)\newline 3x(x7)+5(x7)3x(x - 7) + 5(x - 7)\newline33. Factor out the common binomial factor (x7)(x - 7):\newline (3x+5)(x7)(3x + 5)(x - 7)\newlineStep Output: Factored Form: (3x+5)(x7)(3x + 5)(x - 7)
