sqrt(x^2+9)=1-x

Solution

x^{2} + 9 = 1 - x

Solution

x = - 4

Solution steps

x^{2} + 9 = 1 - x

Square both sides:

x^{2} + 9 = 1 - 2 x + x^{2}

x^{2} + 9 = 1 - 2 x + x^{2}

Solve

x^{2} + 9 = 1 - 2 x + x^{2} : x = - 4

x = - 4

Verify Solutions:

x = - 4

True

The solution is

x = - 4

Popular Examples

(x^2-15)^{1/2}=7

(x^{2} - 15)^{\frac{1}{2}} = 7

x + 1 = - 4

(x - 1)^{\frac{2}{3}} = 0

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

x - 7 - 2 x - 7 = - 2

sqrt(10-x)+sqrt(x+3)=5

10 - x + x + 3 = 5
