The sum of the given terms will be -3x² + 8x - -9.
<h3>What is summation?</h3>
A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation.
There could be only two terms, but there could be one hundred, thousand, or a million. There are summations with an infinite set of parameters.
Given,
(8x - 2) + (-3x² - 7)
Opening bracket
⇒ 8x - 2 - 3x² - 7
Neighbour likely terms
⇒ -3x² + 8x -2 - 7
⇒ -3x² + 8x - 9
Hence the resultant sum of the given equations is -3x² + 8x - 9.
