Answer 1

Question :-

Find the value of expression .

If x=2 , x2-5x +2

Answer :-

x = 2 ,

x2 = 2 × 2 = 4

5x - 2 = 5 × 2 - 2

= 10 - 2 = 8

= 4 - 8

= ( - 4 )

Answer 2

Answer:

=> -4

Step-by-step explanation:

As per the data given in the question, we have to find the value of the expression.

Given that:-

$x^2-5x+2$

If $x = 2$

Now, put the value of x as 2 in the above expression,

So, we get

$=>x^2-5x+2$

The square root of $2$ is $4$

$=>(2)^2-5(2)+2$

$=>4-10+2$

Subtract the numbers,$-4$ and 10.

$=>-6+2$

$=>-4$

Hence, the value of the expression $x^2-5x+2$ is -4.
