x = sq root of 36x = 6x = -6

x2+3=124 x2=121 x= square root(121) x=11

I think you have missed out an equals sign. If you mean x2 + y2 = 16, then the radius is 4.

An equation never equals a number, but its solution often does.-- An equation with a solution of six: [ 3x - 14 = 4 ]-- An equation with a solution of three: [ 14 - 10x = -16 ]-- An equation with both solutions: [ x2 - 9x + 20 = 2 ]An equation that equals 6 is 10 - 4 = 6An equation that equals 3 is 10 - 7 = 3

If x2 = 16 then this is not written as an inequality.An inequality tells us that one thing is not equal to another.The above is an equation, because it is telling us that one thing is equal to another.If x2 = 16 then x = 4 & -4.

x = sq root of 36x = 6x = -6

x2 + 6x = 16=> x2 + 6x - 16 = 0=> x2 + 8x -2x - 16 = 0=> (x+8)(x-2) = 0=> x = -8 or x = 2So, the solutions of the quadratic equation x2 + 6x = 16 are -8 and 2.

x2+3=124 x2=121 x= square root(121) x=11

x2 +y2 = R2 =16 = radius 2 R = 4

It will have two solutions because its a quadratic equation: x = -8.472135955 or x = 0.472135955

If that equals 16 then the radius is 4
