sqrt(7+x)=sqrt(x^2+1)

7 + x = x^{2} + 1

x = 3, x = - 2

Solution steps

7 + x = x^{2} + 1

Square both sides:

7 + x = x^{2} + 1

7 + x = x^{2} + 1

Solve

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

x = 3, x = - 2

Verify Solutions:

x = 3

True

, x = - 2

True

The solutions are

x = 3, x = - 2

y + y + 8 = 2 y

2 x + 19 = x + 8

3 + x + 2 x - 1 = 3

x^{\frac{1}{2}} = 1

\frac{1}{2} y + 7 = 5
