Examples, solutions, videos, worksheets, and activities to help Algebra students learn about factoring simple trinomials for a = 1.
Students learn that a trinomial in the form x2 + bx + c (where c is positive), such as x2 + 7x + 10, can be factored as the product of two binomials, in this case (x + 5)(x + 2).
The first term in each binomial comes from the factors of x2, x and x.
The second term in each binomial comes from the factors of the constant term, +10, that add to the coefficient of the middle term, +7, which in this case are +5 and +2.
Students learn that a trinomial in the form x2 + bx + c (where c is negative),
