Question

Find the following products:
$a) \: ({x}^{2} + \frac{1}{ {x}^{2} } ) \: (x + 1)$
$b) \: (x - \frac{1}{x} ) \: (x + \frac{1}{x} )$
$c) \: {a}^{2} + \frac{3}{2} {b}^{2} ) \: ( {a}^{2} - \frac{3}{2} {b}^{2})$

Answer 1

Step-by-step explanation:

Symbol Command

$\frac {1}{2}$ \frac{1}{2} or \frac12

$\frac{2}{x+2}$ \frac{2}{x+2}

$\frac{1+\frac{1}{x}}{3x + 2}$ \frac{1+\frac{1}{x}}{3x + 2}

Notice that with fractions with a 1-digit numerator and a 1-digit denominator, we can simply group the numerator and the denominator together as one number. However, for fractions with either a numerator or a denominator that requires more than one character (or if the numerator starts with a letter), you need to surround everything in curly brackets
