Work in your book. Type your final answer in the box and press Check. Put brackets round the top and bottom of fractions, like (y+7)/(y-5). Powers: x^2. Square roots: sqrt(7) or √7. Solutions: x = 3 + sqrt(7), x = 3 - sqrt(7) (or use +- for ±). Points: (2, 3), (-3, -2). Inverse: just the expression, e.g. (x+7)/(x-5).
