ok

Is that a quantity cubed all over 2, or to the (3/2) power

3. anonymous

3/2 power

therefore: $x ^{2} - x - 22 = \sqrt[3]{27}^2$ $= x^2 -x -22 = 9$ =$= x^2 -x -31 = 0$ using the quadratic equation: = $(1 + or - \sqrt{1^2-(4 * 1 * -31)}) \div 2$ = 6.09 or -5.09 You can plug these answers int the equation to confirm them.
