Rationalize The Denominator Worksheet

Use the algebraic identity a2 – b2 = (a + b) (a – b) in denominator to simplify. = (x – √y) / [x2 – (√y)2] = (x – √y) / (x2 – y) 3. Answer : = (√x + √y)/√x. Multiply both the numerator and denominator by √x. = (√x + √y)√x / (√x ⋅ √x) Distribute and simplify.

denominator by 2 Simplify 12in the numerator. Choose two numbers that are factors of 12. One of the factors must be a square number 3 Use the rule 4 Use 5 Simplify the fraction: simplifies to Example 3 Rationalise and simplify = = = = = 1 Multiply the numerator and denominator by 25 2252 5 Expand the brackets 3 Simplify the fraction
