(90-x)^{1/2}=x

Solution

(90 - x)^{\frac{1}{2}} = x

Solution

x = 9

Solution steps

(90 - x)^{\frac{1}{2}} = x

Square both sides:

90 - x = x^{2}

90 - x = x^{2}

Solve

90 - x = x^{2} : x = 9, x = - 10

x = 9, x = - 10

Verify Solutions:

x = 9

True

, x = - 10

False

The solution is

x = 9

4-sqrt(2r)=sqrt(2r)-6

4 - 2 r = 2 r - 6

x+16=sqrt(3x^2)

x + 16 = 3 x^{2}

sqrt(2x+6)=4x^2

2 x + 6 = 4 x^{2}

sqrt(5-x+1)=x-2

5 - x + 1 = x - 2
