2x^3y+18xy-10x^2y-90y
= 2xy(x^2 + 9)- 10y(x^2 + 9)
= (x^2 + 9)(2xy - 10y)
= (x^2 + 9) 2y(x - 5)
= 2y (x^2 + 9) (x - 5)

Answer:
Step-by-step explanation:
What you have here is the factored form of the quadratic

where a is the term representing the pull of gravity, b is the upwards vertical velocity and c is the initial height. If we FOIL that out, we get the equation in a form that is easily analyzed for velocity and initial height.

This tells us that the initial vertical velocity of the dive was 10 m/sec, and that she was 15 meters up at the time of diving.
