Answer

Explanation:

Step1: Isolate the square term

Add (49) to both sides of the equation (z^{2}-49 = 0). (z^{2}-49+49=0 + 49) (z^{2}=49)

Step2: Solve for (z)

Take the square root of both sides. Remember that if (x^{2}=a) ((a\geq0)), then (x=\pm\sqrt{a}). Since (z^{2}=49) and (\sqrt{49} = 7), we have (z=\pm7)

Answer:

(7,-7)
