Factoring a trinomial by factoring out common terms first

The video tutorial explains the process of factoring polynomials. It begins with identifying common terms in the polynomial and factoring them out. The instructor then verifies the factoring by multiplying the factors back together. The tutorial continues with factoring trinomials by finding two numbers that multiply to the constant term and add to the linear coefficient. The video emphasizes understanding the relationship between the terms and their coefficients to successfully factor the polynomial.
