Let's name the number 'n'. Now write an equation. 7*n +n^2 =12Now you can form a quadratic. n^2 +7n-12=0. Now you can use a myriad of methods to solve it. If you still need help, just message me.
Given:
The expression is:
![(6m^5+3-m^3-4m)-(-m^5+2m^3-4m+6)](https://tex.z-dn.net/?f=%286m%5E5%2B3-m%5E3-4m%29-%28-m%5E5%2B2m%5E3-4m%2B6%29)
To find:
The resulting polynomial in standard form.
Solution:
We have,
![(6m^5+3-m^3-4m)-(-m^5+2m^3-4m+6)](https://tex.z-dn.net/?f=%286m%5E5%2B3-m%5E3-4m%29-%28-m%5E5%2B2m%5E3-4m%2B6%29)
Write subtraction of a polynomial expression as addition of the additive inverse.
![(6m^5+3-m^3-4m)+(m^5-2m^3+4m-6)](https://tex.z-dn.net/?f=%286m%5E5%2B3-m%5E3-4m%29%2B%28m%5E5-2m%5E3%2B4m-6%29)
Rewrite terms that are subtracted as addition of the opposite.
![6m^5+3+(-m^3)+(-4m)+m^5+(-2m^3)+4m+(-6)](https://tex.z-dn.net/?f=6m%5E5%2B3%2B%28-m%5E3%29%2B%28-4m%29%2Bm%5E5%2B%28-2m%5E3%29%2B4m%2B%28-6%29)
Group like terms.
![[6m^5+m^5]+[3+(-6)]+[(-m^3)+(-2m^3)]+[(-4m)+4m]](https://tex.z-dn.net/?f=%5B6m%5E5%2Bm%5E5%5D%2B%5B3%2B%28-6%29%5D%2B%5B%28-m%5E3%29%2B%28-2m%5E3%29%5D%2B%5B%28-4m%29%2B4m%5D)
Combine like terms.
![7m^5+(-3)+(-3m^3)+0](https://tex.z-dn.net/?f=7m%5E5%2B%28-3%29%2B%28-3m%5E3%29%2B0)
On simplification, we get
![7m^5-3-3m^3](https://tex.z-dn.net/?f=7m%5E5-3-3m%5E3)
Write the polynomial in standard form.
![7m^5-3m^3-3](https://tex.z-dn.net/?f=7m%5E5-3m%5E3-3)
Therefore, the required polynomial in standard form is
.
