Money to be shared=£12
Mick : sharon=2:4
Sum of ratio=2+4=6
Mick share=2/6 x 12
Mick share=(2x12)/6
Mick share=24/6
Mick share=4
Sharon share=4/6 x 12
Sharon share=(4x12)/6

Answer:
roots : 4, -4, i, -i
Step-by-step explanation:
This gets a bit tricky.
We have to substitude x^2 as u in this problem.
Now to rewrite x^4 − 15x^2 − 16 = 0 with u, we get
u^2 - 15u - 16 = 0
( u - 16) (u + 1)
U = 16
U = -1
<em>This is not the end of the problem. </em>
Now we have to substitute x^2 back to u.
x^2 = 16 --> we get the roots 4 and -4
x^2 = -1 --> we get the roots i and -i
tadah!
