<h2>Answer:</h2><h2>−x^2 + 12x + 5</h2><h2>~</h2><h3>Well, to get the answer you need to get both equations.</h3><h3>Let's start with the equation x^2 +3x or
![x^{2} + 3x](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B%203x)
.</h3><h3>All we need to do is factor the variable 'x' out of ''x^2 + 3x'' to get the answer, </h3><h3>x(x + 3) </h3><h2>~</h2><h3>Next we get the other equation, -2x^2 + 9x + 5 or
![2x^{2} + 9x + 5](https://tex.z-dn.net/?f=2x%5E%7B2%7D%20%2B%209x%20%2B%205)
.</h3><h3>Simply add and subtract the second term to the expression and factor by grouping to get the answer, </h3><h3>−(2x + 1) (x − 5)</h3><h2>~</h2><h3>Finally, we take both answers from both equations and simplify the expression, and get the final answer, </h3><h3>−x^2 + 12x + 5</h3><h2>~</h2>
Hope you have a good day, Loves!
