Which expressions are polynomials?
Select each correct answer.
- 6x2 + 5x
- x2 + 5x1/5
- -x2 + 5x
- -7x2 + 5/3x
- y
- 4x3 + y
- 2 + s
- x2 - sqrt of x + 2
+128474 6x^2 + 5x
x^2 + 5x^(1/5)......no fractional powers allowed
-x^2 + 5x
-7x^2 + (5/3)x
y
4x^3 + y
2 + s
- x^2 - sqrt of x + 2 ....... sqrt ( x) = x^(1/2).....no fractional exponents
A plolynomial has constant coefficients associated with each variable and non-negative integer powers on these variables
So....the polynomials are in red
