Introduction
In Factoring Quadratic Trinomials
Factor the first term of the trinomial and write thesw factors as the first term of the factors.
List down all the factors of the last term.
Identify which factor pair sums up the middle term, then
write each factor in the pairs as the lastbterm of the binomial factors.

Conclusion
Factoring Trinomials in the form x2 + bx + c
is a factor trinomial in the formof x2 + bx +c, find two integers, r and s, whose product is c and whose sum is b. Rewrite thetrinomial as x2 + rx + sx + c and then use grouping and the distributive property tofactor the polynomial.
