sqrt(4z+9)=z+1

Solution

4 z + 9 = z + 1

Solution

z = 4

Solution steps

4 z + 9 = z + 1

Square both sides:

4 z + 9 = z^{2} + 2 z + 1

4 z + 9 = z^{2} + 2 z + 1

Solve

4 z + 9 = z^{2} + 2 z + 1 : z = 4, z = - 2

z = 4, z = - 2

Verify Solutions:

z = 4

True

, z = - 2

False

The solution is

z = 4
