Use the quadratic formula to solve for x. 4x²_
-9x-1=0
(If there is more than one solution, separate them with commas.)

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

shorter then the tree

simplified version :

3y^2-10y^2x^4+40x^2+3y^2/2x^2
