(15x^2 - 9x + 9) - (13x^2 + 15x + 5) - (-16x^2 + 20x + 16) - (-7x^2 + 10x - 10)
=15x^2 - 9x + 9 - 13x^2 - 15x - 5 + 16x^2 - 20x - 16 + 7x^2 - 10x + 10
=25x^2-54x-2
=15x^2 - 9x + 9 - 13x^2 - 15x - 5 + 16x^2 - 20x - 16 + 7x^2 - 10x + 10
=25x^2-54x-2

what are you solving here? this isn't an equation. Are you finding the root or are you simplifying?
since you say "solve", it maybe finding the roots. Please be clear
