sqrt(x+3)=x-9

Solution

x + 3 = x - 9

Solution

x = 13

Solution steps

x + 3 = x - 9

Square both sides:

x + 3 = x^{2} - 18 x + 81

x + 3 = x^{2} - 18 x + 81

Solve

x + 3 = x^{2} - 18 x + 81 : x = 13, x = 6

x = 13, x = 6

Verify Solutions:

x = 13

True

, x = 6

False

The solution is

x = 13

10 π = 5 + π 100 - x^{2}

sqrt(x^2-x-2)=0

x^{2} - x - 2 = 0

2x=sqrt(-9x+27)-3

2 x = - 9 x + 27 - 3

x + 4 - 3 x = 3

sqrt(x+2)+sqrt(x+7)=5

x + 2 + x + 7 = 5
