Answer 1

The sum of the given terms will be -3x² + 8x - -9.

What is summation?

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.
