What is factoring in algebra?

Back

Factoring is the process of breaking down an expression into a product of simpler expressions, called factors.

What does it mean when a > 1 in factoring?

Back

It means that the leading coefficient of the quadratic expression is greater than 1, which affects how we factor the expression.
