sqrt(2x+2)=x-3

Solution

2 x + 2 = x - 3

Solution

x = 7

Solution steps

2 x + 2 = x - 3

Square both sides:

2 x + 2 = x^{2} - 6 x + 9

2 x + 2 = x^{2} - 6 x + 9

Solve

2 x + 2 = x^{2} - 6 x + 9 : x = 7, x = 1

x = 7, x = 1

Verify Solutions:

x = 7

True

, x = 1

False

The solution is

x = 7

Popular Examples

sqrt(2x+6)-sqrt(x+1)=2

2 x + 6 - x + 1 = 2

sqrt(x+19)+sqrt(x-2)=7

x + 19 + x - 2 = 7

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

x + 2 = 2 x - 1

sqrt(8x-39)+12=13

8 x - 39 + 12 = 13

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

2 x + 2 - x - 3 = x + 9
