If x = 5 – 2V6 , then find the value of x² + 1 - 2

::48 - 20V6

Step-by-step explanation:

Here,

x= 5 - 2V6

Now,

x^2 +1-2

= (5 - 2V6) ^2 +1 - 2

= 5^2 - 2*5*2V6 + (2V6)^2 +1 - 2

= 25 - 20V6 +4*6 +1 - 2

= 25 - 20V6 +24 +1 - 2

= 25 +24 +1 - 2-20V6

= 48 - 20V6

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
