Answer: The answer is [tex]-5x^2-25x+3.[/tex]
Step-by-step explanation: We are to find the simplest form of the following expression:
[tex]E=2x(x-6)-7x^2-(13x-3).[/tex]
The simplification is as follows:
[tex]E\\\\=2x(x-6)-7x^2-(13x-3)\\\\=2x^2-12x-7x^2-(13x-3)\\\\=-5x^2-12x-(13x-3)\\\\=-5x^2-12x-13x+3\\\\=-5x^2-25x+3.[/tex]
Thus, the simplified form of the given expression is [tex]-5x^2-25x+3.[/tex]
