solvefor x,sqrt(2x+10)=-x-1

x, 2 x + 10 = - x - 1

x = - 3

Solution steps

2 x + 10 = - x - 1

Square both sides:

2 x + 10 = x^{2} + 2 x + 1

2 x + 10 = x^{2} + 2 x + 1

Solve

2 x + 10 = x^{2} + 2 x + 1 : x = 3, x = - 3

x = 3, x = - 3

Verify Solutions:

x = 3

False

, x = - 3

True

The solution is

x = - 3

6 x - 3 = 9 x + 19

4 + x + 5 = 10

H^{1.53} \cdot 0.535 = 0.04167

3 + 7 x - 3 = x
