Study GuideAlgebra I–Algebraic FracƟons1. What Are Algebraic FracƟons?Algebraic fractions are just like normal fractions—but they includevariables(letters like x, a, or b).For example:Here,xis a variable in the denominator.So, an algebraic fraction is any fraction that has:•A variable in the numerator, or•A variable in the denominator, or•Variables in both.Why Do We Have Restrictions?You already know something very important:Division by 0 is impossible.Because of this, any value that makes the denominator equal to0is not allowed.That means:The denominator of a fraction can never be zero.So whenever we see an algebraic fraction, we must check what values would make the denominatorzero—and exclude them.These excluded values are calledrestrictions.Preview Mode
