the quantity 3 times x to the third power plus 5 times x plus 2 all over x
3x3 + 5x + 2
3x2 + 5x2 + 2x
3x5 + 5x3 + 2x2

Answer 1

A: 3^3 + 5x + 2/x

Explanation:

Answer 2

(A)
`3x^3+5x+2`

Explanation:

To Simplify: The quantity 3 times x to the 4th power plus 5 times x to the 2nd power plus 2 times x all over x.

Solution: The given statement can be easily rewritten as:

`The quantity 3 times x to the 4th power=3x^4`,

`5 times x to the 2nd power=5x^2` and

`2 times x =2x`

Thus, according to the statement, the expression can be written as:

`(3x^4+5x^2+2x)/(x)`

⇒
`3x^3+5x+2`

which is the required simplified expression.

Thus,option A is correct.
