2sqrt(2N+5)=N

Solution

2 2 N + 5 = N

Solution

N = 10

Solution steps

2 2 N + 5 = N

Square both sides:

8 N + 20 = N^{2}

8 N + 20 = N^{2}

Solve

8 N + 20 = N^{2} : N = 10, N = - 2

N = 10, N = - 2

Verify Solutions:

N = 10

True

, N = - 2

False

The solution is

N = 10

-sqrt(2a-1)=-2sqrt(5a-4)

- 2 a - 1 = - 2 5 a - 4

sqrt(2x+1)+1=sqrt(x+4)

2 x + 1 + 1 = x + 4

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

x = 2 - x + 1

sqrt(3z+25)+6=z+5

3 z + 25 + 6 = z + 5

(sqrt(6x+21)+3)^2=(x-2)^2

(6 x + 21 + 3)^{2} = (x - 2)^{2}
