How do you subtract rational expressions
WebHow to Subtract Rational Expressions? We can subtract rational expressions with like denominators by applying similar steps in addition. Let’s take a look at some examples: Example 6 Subtract 4/ (x+1) – 1/ (x + 1) Solution Subtract the numerators by keeping the denominators; Hence, 4/ (x+1) – 1/ (x + 1) = (4- 1)/ / (x + 1) = 3/x +1 WebWhen adding or subtracting two or more rational expressions with common denominators, we add or subtract only the numerator while we keep the denominator the same. We will then simplify...
