Practice problem
Simplify the following expression: x2+2x+13÷x2−16\frac{x^{2}+2x+1}{3} \div \frac{x^{2}-1}{6}3x2+2x+1÷6x2−1
2x+2x−1\frac{2x+2}{x-1}x−12x+2
2x2+4x+2x2−1\frac{2x^{2}+4x+2}{x^{2}-1}x2−12x2+4x+2
2x+2x+1\frac{2x+2}{x+1}x+12x+2
(x+1)3(x−1)18\frac{(x+1)^{3}(x-1)}{18}18(x+1)3(x−1)
Type a concept, like “slope” or “photosynthesis”.
