Identify Coefficients: Identify the coefficients of the quadratic expression.The quadratic expression is 6x2+5x−14. Here, the coefficient of x2(a) is 6, the coefficient of x(b) is 5, and the constant term (c) is −14.
Find Factor Pairs: Find two numbers that multiply to ac (6×−14=−84) and add up to b (5).We need to find two numbers that multiply to −84 and add up to 5. After checking possible factor pairs of −84, we find that 12 and −7 multiply to −84 and add up to 5.
Rewrite Middle Term: Rewrite the middle term using the two numbers found in Step 2.We can express 5x as 12x−7x, which are the two numbers that add up to 5 and multiply to −84. So, the expression becomes 6x2+12x−7x−14.
Factor by Grouping: Factor by grouping.Now we group the terms to factor by grouping: 6x^2 + 12x) - (7x + 14)\. We can factor out a common factor of \$6x from the first group and (-7\)\ from the second group: 6x(x+2)−7(x+2).
Factor out Common Factor: Factor out the common binomial factor.Since both groups contain the common binomial factor (x+2), we can factor it out: (6x−7)(x+2).
