On performing the indicated operation, we get the following result: -9a³ -22a² +7a +9
Polynomials are algebraic expressions that are made up of only variables and coefficients.
Here, we ae given an polynomial expression as follows-
(-5a³ -7a² +10) - (2a³ +8a² -2a -1) + (-2a³ -7a² +5a -2)
To solve this, we first open the brackets as follows-
= -5a³ -7a² +10 -2a³ -8a² +2a +1 -2a³-7a² +5a -2
Now, we bring the terms with the same powers together as follows-
= -5a³ -2a³ -2a³ -7a² -8a² -7a² +2a +5a +1 -2 +10
= -9a³ -22a² +7a +9
Thus, on performing the indicated operation, we get the following result- -9a³ -22a² +7a +9
