Answer 1

To simplify this expression, we'll start by combining the two fractions inside the numerator:

[start fraction, 1, divided by, x, end fraction, plus, start fraction, 1, divided by, x squared, end fraction, divided by, start fraction, 1, divided by, x, end fraction]

To combine these fractions, we need to find a common denominator. The common denominator for x and x squared is x squared:

[start fraction, (1/x), multiplied by, (x squared/x squared), plus, (1/x squared), multiplied by, (x/x), end fraction, divided by, (1/x)]

Simplifying the numerators, we have:

[start fraction, (x squared/x squared), plus, (x/x squared), end fraction, divided by, (1/x)]

Simplifying further:

[start fraction, x squared/x squared, plus, x/x squared, end fraction, divided by, 1/x]

Now, we can divide the terms in the numerator by their common denominator:

[start fraction, (x squared + x)/x squared, end fraction, divided by, 1/x]

Dividing by a fraction is the same as multiplying by its reciprocal:

[start fraction, (x squared + x)/x squared, end fraction, multiplied by, x/1]

Multiplying the numerators and denominators, we get:

(start fraction x squared + x) over (x squared multiplied by 1) multiplied by x over 1

Simplifying further:

(x squared + x)/(x squared) multiplied by x/1

Simplifying the multiplication:

(x squared + x) times x/x squared = x squared + x squared = 2x squared.

So the fully simplified expression is 2x squared.
