x=sqrt(4x+5)

Solution

x = 4 x + 5

Solution

x = 5

Solution steps

x = 4 x + 5

Square both sides:

x^{2} = 4 x + 5

x^{2} = 4 x + 5

Solve

x^{2} = 4 x + 5 : x = 5, x = - 1

x = 5, x = - 1

Verify Solutions:

x = 5

True

, x = - 1

False

The solution is

x = 5

Popular Examples

x+12-3sqrt(x+22)=0

x + 12 - 3 x + 22 = 0

sqrt(x+5)+sqrt(2)=sqrt(x+7)

x + 5 + 2 = x + 7

sqrt(x-3)=x^2-9x

x - 3 = x^{2} - 9 x

p^{(-5)/2}= 1/32

p^{\frac{- 5}{2}} = \frac{1}{32}

(x + 3)^{\frac{3}{2}} = 64
