Solve and Check 5z^2=-500

= -500

First, divide both sides by 5. / Your problem should look like: 
Second, simplify  to 100. / Your problem should look like: 
Third, take the square root of both sides. / Your problem should look like:  , 
Fourth, simplify  to  / Your problem should look like: z = ±
Fifth, 10 × 10 = 100, so the square root of 100 is 10. / Your problem should look like: z = ±10i

 z = ±10i OR z = 10i, -10i
