Welcome, thank you
Evaluate [(x + 2y-3 / 2) (x-2y +) + 2Y (3 / 2 -)] / (- 3x) - 1, where x = - 1, y = 2006 / 2007
3 / 2 means 3 / 2, (3 / 2 -) means 3 / 2 of the negative quadratic power, (- 3x) - 1 means negative 3x, and 2006 / 2007 means 2006 / 07,
-3x square plus 12Y square plus 9 / 2 x-35 y
Given x2 + y2-8x-10y + 41 = 0, find y / x2-xy + X / y2-xy
This is the result of 178;; + y-y-\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\178
