Question

X²-46+17÷2, if the value of x is 7

Answer 1

Given :

Equation ,  $x^{2} - 46$ + 17 ÷ 2

To find :

The value of equation if x = 7

Solution :

Simplifying the equation we get ,

                                     = $x^{2} - 46 + \frac{17}{2}$  

Now , applying BODMAS rule , and substituting x = 7 we get,

                                     = $(7)^{2} - 46 + \frac{17}{2}$

                                     = $49 - 46 + 8.5$

                                     = $49 - 37.5$

                                     = $11.5$

Final answer :

Hence , the value of  " $x^{2} - 46 + \frac{17}{2}$" at $x = 7$ is $11.5$ .
