Answer:
Step-by-step explanation:
8x² + 2(x²-1) = 8x² + 2*x² - 2*1
= 8x² + 2x² -2
= 10x² -2
Like terms: 8x² , 2x²
Answer:
is not a polynomial.
Step-by-step explanation:
Given : an expression ![X^{-6}](https://tex.z-dn.net/?f=X%5E%7B-6%7D)
We have to check whether given expression
is a polynomial or not.
An expression is said to be polynomial if it is the collection of constant and one or several variables having non negative integer power or degree.
Example : ![2x^2+3x+1, x^5,m^2+n^5](https://tex.z-dn.net/?f=2x%5E2%2B3x%2B1%2C%20x%5E5%2Cm%5E2%2Bn%5E5)
For the given expression
the variable term is X is having power of -6 which is negative.
Hence,
is not a polynomial.
