Answer :
Given: The below
[tex](3x^2+5x-6)-(4x^2+7x-3)[/tex]To: Simplify the given expressions
Solution
[tex]\begin{gathered} (3x^2+5x-6)-(4x^2+7x-3) \\ 3x^2+5x-6-4x^2-7x+3 \\ Collect\text{ like terms} \\ 3x^2-4x^2+5x-7x-6+3 \\ -x^2-2x-3 \end{gathered}[/tex]Hence the simplified form is - x² - 2x - 3
