Question

The value of the expression (2x^2)/(x) + x(100-15x) when x = 5 is

Answer 1

45 is the answer for the expression

Answer 2

`(2x^2)/(x) + x(100-15x)` at x=5

135

Explanation:

Given: The expression
`(2x^2)/(x) + x(100-15x)`

This is rational expression of variable x.

Put x=5 into the expression and then simplify

`\Rightarrow (2\cdot 5^2)/(5) + 5(100-15\cdot 5)`

`\Rightarrow 2\cdot 5 + 5(100-75)`

`\Rightarrow 2\cdot 5 + 5\cdot 25)`

`\Rightarrow 10+125` (Addition of two integer)

`\Rightarrow 135`

Hence, The value of given expression is 135
