.=25x^2-54x-2-what are you solving here? this isnt an equation. Are you finding the root or are you simplifying?since you say solve, it maybe finding the roots.......
the solution on this polynomial expressions
please help...thanks

(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

since you say "solve", it maybe finding the roots. Please be clear
