## anonymous one year ago Solve the equation x ^1/4 = -4x^1/2 + 22. Plot both sides of the equation in the same viewing screen, y1= x^1/4 and y2=-4x^1/2+22. Does the point(s) of intersection agree with your solution?

let u=x^(1/4)

2. anonymous

and u^2=x^(1/2)

3. anonymous

then solve it as quadratic equation.

4. anonymous

u=-4u^2+22

5. anonymous

are you with me?

6. anonymous

4u^2+u-22=0

7. anonymous

use Quadratic Formula to solve it http://prntscr.com/8am6wc

this the final answer try to find it x= $\frac{ ({\sqrt{353}-1})^4 }{ 4096}$
