Question 1116389
(a,3):
{{{x^2=34-y^2}}}
{{{x=0+- sqrt(34-y^2)}}}
{{{x=0+- sqrt(34-3^2)}}}
{{{x=0+- sqrt(34-9)}}}
{{{x=0+- 5}}}


Do both of these values work?
{{{(5)^2+3^2=34}}}
{{{25+9=34}}}
{{{34=34}}}
-
{{{(-5)^2+9=34}}}
{{{25+9=34}}}
-
x=-5, or, x=5.
Either of these work in the equation.


You can solve for b, in the same way.
