There are three sets of factoring trinomials worksheets:
- Factoring Trinomials (a = 1)
- Factoring Trinomials (a > 1)
- Factor Perfect Square Trinomials
Examples, solutions, videos, and worksheets to help Grade 6 and Grade 7 students learn how to factor trinomials, ax 2 + bx + c for a = 1.
How to factor trinomials?
There are five sets of factoring trinomials worksheets (a = 1).
- Factor Trinomials (b>0, c>0).
- Factor Trinomials (b>0, c <0).
- Factor Trinomials (b0).
- Factor Trinomials (b
- Factor Trinomials (b & c can be positive or negative).
These are the steps to factor trinomials:
- Make sure the trinomial is written in standard form, which is in the form of ax 2 + bx + c, where a, b, and c are constants.
- Look for any common factors among the coefficients (a, b, and c) and factor them out. This step is important to simplify the trinomial before further factoring.
- Identify two numbers that multiply to give the constant term (c) and add up to give the coefficient of the middle term (b).
- Rewrite the middle term (bx) using the two numbers found in the previous step.
- Group the terms of the trinomial by grouping the first two terms and the last two terms.
- Factor out the greatest common factor (GCF) from each group, if possible.
- Apply the distributive property to factor out the common binomial factor.
Example: Factor the trinomial x 2 - 6x + 5.
- The trinomial is already in standard form.
- There are no common factors among the coefficients.
- The numbers that multiply to give 5 and add up to give -6 are -5 and -1.
- Rewrite the middle term:
x 2 - 5x - x + 5
- Group the terms:
(x 2 - 5x) + (-x + 5)
- Factor out the GCF from each group:
x(x - 5) - 1(x - 5)
- Apply the distributive property:
(x - 1)(x - 5)
Therefore, the factored form of the trinomial x 2 - 6x + 5 is (x - 1)(x - 5).
