Identify a, b, c: Identify a, b, and c in the quadratic expression 2f2−7f+6. Compare 2f2−7f+6 with ax2+bx+c. a=2b0b1
Find two numbers: Find two numbers whose product is a∗c (2∗6=12) and whose sum is b (−7).We need to find two numbers that multiply to 12 and add up to −7.−3∗−4=12−3+−4=−7Two numbers: −3, −4
Rewrite middle term: Rewrite the middle term −7f using the two numbers found in Step 2.2f2−7f+6 can be rewritten as 2f2−3f−4f+6.
Factor by grouping: Factor by grouping.Group the terms: 2f2−3f + −4f+6.Factor out the common factors from each group.f(2f−3)−2(2f−3).
Factor common binomial: Factor out the common binomial factor.The common binomial factor is (2f−3).The factored form is (f−2)(2f−3).
