Answer: ![5x^2-x+4](https://tex.z-dn.net/?f=5x%5E2-x%2B4)
Step-by-step explanation:
In addition of polynomials, you only have to add the like terms.
Remember the multiplication of signs:
![(+)(+)=+\\(-)(-)=+\\(-)(+)=-](https://tex.z-dn.net/?f=%28%2B%29%28%2B%29%3D%2B%5C%5C%28-%29%28-%29%3D%2B%5C%5C%28-%29%28%2B%29%3D-)
Then, given the polynomial
and the polynomial
, you can find the sum of them by adding the like terms.
Observe the procedure below:
![(12x^2+3x+6)+(-7x^2-4x-2)=12x^2+3x+6-7x^2-4x-2=5x^2-x+4](https://tex.z-dn.net/?f=%2812x%5E2%2B3x%2B6%29%2B%28-7x%5E2-4x-2%29%3D12x%5E2%2B3x%2B6-7x%5E2-4x-2%3D5x%5E2-x%2B4)
Therefore, the sum is:
![5x^2-x+4](https://tex.z-dn.net/?f=5x%5E2-x%2B4)
Answer:
(m - 3n)(m + 3n).
Step-by-step explanation:
This is the difference of 2 squares, so we use the identity:
a^2 - b^2 = (a - b)(a + b).
So m^2 - 9n^2
(m - 3n)(m + 3n).
Answer:
1/72
Step-by-step explanation:
2^-3 = 1/2^3 = 1/8
3^-2 = 1/3^2 = 1/9
1/8 x 1/9 = 1/72
