Q. Factor completely.\newline2x2+9x35 2 x^{2}+9 x-35 \newlineAnswer:
  1. Identify quadratic expression: Identify the quadratic expression to be factored.\newlineThe given expression is 2x2+9x352x^2 + 9x - 35.
  2. Find suitable numbers: Look for two numbers that multiply to give the product of the coefficient of x2x^2 (which is 22) and the constant term (which is 35-35), and add up to the coefficient of xx (which is 99).\newlineThe product of the coefficient of x2x^2 and the constant term is 2×(35)=702 \times (-35) = -70.\newlineWe need two numbers that multiply to 70-70 and add up to 99.\newlineThe numbers 1414 and 2200 satisfy these conditions because 2211 and 2222.
  3. Rewrite middle term: Rewrite the middle term 9x9x using the two numbers found in the previous step.\newlineThe expression 2x2+9x352x^2 + 9x - 35 can be rewritten as 2x2+14x5x352x^2 + 14x - 5x - 35.
  4. Factor by grouping: Factor by grouping.\newlineGroup the terms to factor common terms out of each group.\newline(2x2+14x)(5x+35)(2x^2 + 14x) - (5x + 35)\newlineFactor out 2x2x from the first group and 5-5 from the second group.\newline2x(x+7)5(x+7)2x(x + 7) - 5(x + 7)
  5. Factor out common binomial: Factor out the common binomial factor (x+7)(x + 7). The expression now becomes (2x5)(x+7)(2x - 5)(x + 7).
