sqrt(5+2x)=-x-1

Solution

5 + 2 x = - x - 1

Solution

x = - 2

Solution steps

5 + 2 x = - x - 1

Square both sides:

5 + 2 x = x^{2} + 2 x + 1

5 + 2 x = x^{2} + 2 x + 1

Solve

5 + 2 x = x^{2} + 2 x + 1 : x = 2, x = - 2

x = 2, x = - 2

Verify Solutions:

x = 2

False

, x = - 2

True

The solution is

x = - 2

sqrt(7x)+1=sqrt(10x-6)

7 x + 1 = 10 x - 6

x^{1/2}-6x^{1/4}+5=0

x^{\frac{1}{2}} - 6 x^{\frac{1}{4}} + 5 = 0

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

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

sqrt(4x-32-16)=-14

4 x - 32 - 16 = - 14

2 x = 10
