What is factoring in mathematics?

Back

Factoring is the process of breaking down an expression into a product of simpler expressions, or factors, that when multiplied together give the original expression.

What does GCF stand for in factoring?

Back

GCF stands for Greatest Common Factor, which is the largest factor that divides two or more numbers or expressions.

How do you factor the expression x^4 - 9x^2?

Back

Factor out the GCF first: x^2(x^2 - 9), then recognize x^2 - 9 as a difference of squares: x^2(x + 3)(x - 3).

How do you factor the expression 3x^2 + 18x + 15?

Back

First, factor out the GCF: 3(x^2 + 6x + 5), then factor the quadratic: 3(x + 5)(x + 1).

What is the first step in factoring a polynomial?

Back

The first step is to check if there is a GCF (Greatest Common Factor) among the terms.
