Step-by-step explanation:
DC+ da+ bc -180
so now you can calculate
Answer:
40
Step-by-step explanation:
![20 + 20 = 40](https://tex.z-dn.net/?f=20%20%2B%2020%20%3D%2040)
That is literally all there is to it
The pattern is multiplying each number by 4
Answer: ![2x^3+2x](https://tex.z-dn.net/?f=2x%5E3%2B2x)
Step-by-step explanation:
The difference is obtained by subtracting the polynomial
and the polynomial
.
It is important to remember the multiplication of signs:
![(-)(-)=+\\(+)(+)=+\\(-)(+)=-](https://tex.z-dn.net/?f=%28-%29%28-%29%3D%2B%5C%5C%28%2B%29%28%2B%29%3D%2B%5C%5C%28-%29%28%2B%29%3D-)
Then, you can subtract both polynomials to find the difference.
You need to Distribute the negative sign:
![(x^4+x^3+x^2+x)-(x^4-x3+x^2-x)=x^4+x^3+x^2+x-x^4+x3-x^2+x](https://tex.z-dn.net/?f=%28x%5E4%2Bx%5E3%2Bx%5E2%2Bx%29-%28x%5E4-x3%2Bx%5E2-x%29%3Dx%5E4%2Bx%5E3%2Bx%5E2%2Bx-x%5E4%2Bx3-x%5E2%2Bx)
Finally, you have to add the like terms. Then:
![=2x^3+2x](https://tex.z-dn.net/?f=%3D2x%5E3%2B2x)
