Question

Polynomials : add , subtract, multiply and divide bare minimum of steps please

Answer 1

We are given the following polynomials:

`(7a^2-4a+5)-(3a^2+5a-3)`

First, we need to change the sing of the terms insides the second parenthesis since it is preceded by a minus sign:

`7a^2-4a+5-3a^2-5a+3`

Now we will add like terms, that is, terms that have the same variable elevated to the same exponent. Like this:

`(7a^2-3a^2)+(-4a-5a)+(5+3)`

Now we add the coefficients of each like term:

`4a^2-9a+8`

Since we can't simplify any further this is the answer.
