Adding and Subtracting Rational Expressions
Master Adding and Subtracting Rational Expressions in Grade 10 math. Think of a rational expression as a fancy fraction, but instead of just numbers, it has polynomials .
Key Concepts
New Concept A rational expression is a ratio of polynomials: $\frac{f(x)}{g(x)}$, for polynomials $f(x)$ and $g(x)$, where $g(x) \neq 0$ and is of degree $\geq 1$.
What’s next Next, you’ll practice adding and subtracting these expressions by finding a common denominator, just like with numerical fractions.
Common Questions
What is Adding and Subtracting Rational Expressions?
Think of a rational expression as a fancy fraction, but instead of just numbers, it has polynomials (expressions with variables like ) on the top and bottom. The most important rule is that the bottom part, the denominator, can never be zero, because dividing by zero is undefined in math! This...
