sqrt(x+7)=1+x

Solution

x + 7 = 1 + x

Solution

x = 2

Solution steps

x + 7 = 1 + x

Square both sides:

x + 7 = 1 + 2 x + x^{2}

x + 7 = 1 + 2 x + x^{2}

Solve

x + 7 = 1 + 2 x + x^{2} : x = 2, x = - 3

x = 2, x = - 3

Verify Solutions:

x = 2

True

, x = - 3

False

The solution is

x = 2

Popular Examples

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

x + x - 4 = 2

sqrt(1+4\sqrt{x)}=sqrt(x)+1

1 + 4 x = x + 1

sqrt(5x+6)+3=sqrt(3x+3)+4

5 x + 6 + 3 = 3 x + 3 + 4

(4x-16)^{1/2}=36

(4 x - 16)^{\frac{1}{2}} = 36

sqrt(9-x)+2=x-5

9 - x + 2 = x - 5
