Factoring Trinomials with Positive Constants
Question
Factoring Trinomials with Positive Constants
Solution
Sure, I can help with that. Factoring trinomials with positive constants involves a few steps. Here's a step-by-step guide:
Step 1: Identify the trinomial to be factored. A trinomial is a polynomial with three terms. For example, 2x^2 + 7x + 3 is a trinomial.
Step 2: Identify the coefficients of the trinomial. The coefficients are the numbers in front of the variables. In the example above, the coefficients are 2, 7, and 3.
Step 3: Multiply the coefficient of the x^2 term (in this case, 2) by the constant term (in this case, 3). This gives you 6.
Step 4: Look for two numbers that multiply to give you the number from step 3 (6), and add to give you the coefficient of the x term (7). The numbers that fit this are 6 and 1, because 6*1 = 6 and 6+1 = 7.
Step 5: Rewrite the middle term of the trinomial as the sum of the terms found in step 4. This gives you 2x^2 + 6x + x + 3.
Step 6: Factor by grouping. Group the first two terms together and the last two terms together, and factor out the greatest common factor from each group. This gives you 2x(x + 3) + 1(x + 3).
Step 7: Notice that the terms in the parentheses are the same. You can factor out this common binomial, giving you the final factored form of the trinomial: (2x + 1)(x + 3).
And that's how you factor trinomials with positive constants!
