x^2(x^2+1)-3(x^2+1)=0\\
(x^2-3)(x^2+1)=0\\
x^2-3=0 \vee x^2+1=0\\
x^2=3 \vee x^2=-1\\
x=-\sqrt3 \vee x=\sqrt3 \vee x=-i \vee x=i$

I use 1/12 of my salary to pay for rates and taxes,1/16 to pay for insurance and 5/6 to meet other expenses. if i have r320 left

omeli [17]

The yearly salary after paying for taxes, insurances and other expenses is r808.42.

<h3>What is the yearly salary?</h3>

The first step is to determine the total fraction used to pay for taxes, insurances and other expenses:

1/2 + 1/16 + 5/6

(48 + 6 + 80) / 96 = 134 / 96= 1 19/48

Now subtract 1 19/48 from 1

1 19/48 - 1 = 19/48

Finally, divide 19/48 by 320

320 x 48/19 = r808.42
