Question

the simplest form of (2n-1) (3n+2) -(6n-5) =
​

Answer 1

Answer:

6n2−5n+3

Step-by-step explanation:

Distribute the Negative Sign:

=(2n−1)(3n+2)+−1(6n−5)

=(2n−1)(3n+2)+−1(6n)+(−1)(−5)

=(2n−1)(3n+2)+−6n+5

Distribute:

=(2n)(3n)+(2n)(2)+(−1)(3n)+(−1)(2)+−6n+5

=6n2+4n+−3n+−2+−6n+5

Combine Like Terms:

=6n2+4n+−3n+−2+−6n+5

=(6n2)+(4n+−3n+−6n)+(−2+5)

=6n2+−5n+3
