Question

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?

Answer 1

let u=x^(1/4)

Answer 2

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

Answer 3

then solve it as quadratic equation.

Answer 4

u=-4u^2+22

Answer 5

are you with me?

Answer 6

4u^2+u-22=0

Answer 7
