Solve the equation without the use of a calculator. ! ! 9x=10-x^2

Essentially, you are being asked to factor

... x^2 +9x -10 = 0

That is, you are looking for factors of -10 that add to +9. It doesn't take long to find that -1 and 10 add to +9, so the factorization is

... (x -1)(x +10) = 0

The solutions are the values of x that make these factors zero.

... x = 1 or x = -10
