Factoring quadratic expressions is a fundamental concept in algebra that often appears in various mathematical and real-world problems. In this comprehensive blog post, we will delve into the art of factoring, focusing on the step-by-step process to factor quadratic expressions effectively. Our primary example for this journey will be the quadratic expression 3x^2 + 7x – 6, which we will factor completely. By the end of this post, you’ll have a clear understanding of the techniques and strategies needed to factor even the most complex quadratic expressions.
Factor Completely. 3x^2+7x-6
To factor completely, we break down the quadratic expression 3x^2 + 7x – 6 into two binomial factors:
3x^2 + 7x – 6 = (3x – 2)(x + 3).
The factored form is (3x – 2)(x + 3), where (3x – 2) and (x + 3) are the binomial factors representing the original expression’s complete factorization.
