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.

What is the 'ac method' in factoring?

Back

The 'ac method' involves multiplying the leading coefficient (a) by the constant term (c) to find two numbers that multiply to ac and add to b.
