Final answer:
To multiply the rational expressions, multiply the numerators and denominators together.
Step-by-step explanation:
To multiply the rational expressions, we multiply the numerators together and multiply the denominators together. In this case, we have:
(11x²+10xy-y²) / (11x²-12xy+y²) * (x²-y²) / (x²+2xy+y²)
When we multiply the numerators, we get (11x²+10xy-y²)(x²-y²). When we multiply the denominators, we get (11x²-12xy+y²)(x²+2xy+y²).
Combining these two expressions, we get:
((11x²+10xy-y²)(x²-y²)) / ((11x²-12xy+y²)(x²+2xy+y²))
Further simplification may be possible by factoring and canceling out common terms.
