First step in solving this equation is to multiply the terms (x+9) by (2x-9) using the F.O.I.L. method. First, Outer, Inner and Last.
your equation then becomes:
2x^2 - 9x + 18x - 81
reduce, simply and add like terms and the result will be:
2x^2 + 9x - 81

(x+9)(2x-9)
=x(2x-9)+ 9(2x-9)
= 2x^2 - 9x + 18x -81
=2x^2 +9x -81
