###### Question details

Please explain these in detail. I have Tried them but got them
wrong.

Perform the indicated operations and simplify

4x+19/6x-1 - 2x+19/6x-1
x/x^2+x-12 - 1/x+4

Simply the expression

-sqrt x^2+2/x^2 + 1/sqrt x^2+2

X(x+6)^1/2-(x+6)^1/2 / x^2

3x^2/9(x^2-1)^2/3 - (x^2-1)^1/3 all divides by x^2

-x/5(6+x^2)^3/2 + 6/(6+x^2)^1/2

Rationalize the denominator and simplify

2y/sqrt y+7

X/sqrt 6 - sqrt 7

Rationalize the numerator and simply

Sqrt x+9 -3/x (-3 is not in sqrt)

Much thanks! If any of the problems I typed don’t make sense
