Answer:
[tex]-\frac{9\sqrt{10} }{5}[/tex], [tex]\frac{9\sqrt{10} }{5}[/tex]
Step-by-step explanation:
[tex](5*\frac{x}{3}) * (5*\frac{x}{5} ) = 54\\[/tex] calculate the product
[tex]\frac{5x}{3} * x =54[/tex] multiply
[tex]\frac{5x^{2} }{3} = 54[/tex] multiply both sides by [tex]\frac{3}{5}[/tex]
[tex]x^{2} =\frac{162}{5}[/tex] separate into two solutions
x = ± [tex]\frac{9\sqrt{10} }{5}[/tex]
