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

Solution

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

Solution

x = 4

Solution steps

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

Square both sides:

x^{2} + 9 = 4 x^{2} - 12 x + 9

x^{2} + 9 = 4 x^{2} - 12 x + 9

Solve

x^{2} + 9 = 4 x^{2} - 12 x + 9 : x = 4, x = 0

x = 4, x = 0

Verify Solutions:

x = 4

True

, x = 0

False

The solution is

x = 4

Popular Examples

x + 5 = 7 - x

sqrt((x-7)^2)=x-7

(x - 7)^{2} = x - 7

2 x - 1 = 1
