sqrt(2a-5)=a-4

Solution

2 a - 5 = a - 4

Solution

a = 7

Solution steps

2 a - 5 = a - 4

Square both sides:

2 a - 5 = a^{2} - 8 a + 16

2 a - 5 = a^{2} - 8 a + 16

Solve

2 a - 5 = a^{2} - 8 a + 16 : a = 7, a = 3

a = 7, a = 3

Verify Solutions:

a = 7

True

, a = 3

False

The solution is

a = 7
