Choose the solutions of the following systems of equations x^2+y^2=6 and x^2-y=6
den301095 [7]

Answer:

The solutions are (-√6,0) and (√6,0)

(-√5,-1) and (√5,-1)

Step-by-step explanation:

The equations are:

{x}^{2}  +  {y}^{2}  = 6

and

{x}^{2}  - y = 6

We make y the subject in the second equation to get;

y =  {x}^{2}  - 6

We substitute into the first equation to get:

{x}^{2}  +  ({x}^{2}  - 6 )^2= 6

x =  \pm \sqrt{6}

and x =  \pm \sqrt{5}

The solutions are (-√6,0) and (√6,0)

(-√5,-1) and (√5,-1)
