1. anonymous

write 17 as sum of 15 and 2

2. amistre64

if u = x^2 then: 6x^4-17x^2+5 =0 | | | | 6u^2 -17u +5 =0

3. amistre64

when you know the values for "u"; you can solve for "x"

4. dumbcow

x= sqrt(3)/3, sqrt(10)/2

+- cow....+- ;)

mr.cow how would i write that

7. dumbcow

$\pm \frac{\sqrt{3}}{3}, \pm \frac{\sqrt{10}}{2}$

8. anonymous

im suppose to solve the equation for x when i key that in its saying incorrect answer

9. dumbcow

did you split up the plus and minus they prob want 4 distinct answers

10. dumbcow

or maybe they want a decimal approximation
