Answer:

(

z

+

22

)(

z

22

)=35

Subtract both sides from 35

(\sqrt{z}+\sqrt{22} (\sqrt{z} -\sqrt{22})-35=35-35(

z

+

22

(

z

22

)−35=35−35

Simplify:

(\sqrt{z})^{2} -57=0(

z

)

2

−57=0

Factor (\sqrt{z})^{2} -57: (\sqrt{z}+\sqrt{57}) (\sqrt{z}-\sqrt{57})(

z

)

2

−57:(

z

+

57

)(

z

57

) =0

\sqrt{z} +\sqrt{57}=0 or \sqrt{z} -\sqrt{57}=0

z

+

57

=0or

z

57

=0

\sqrt{z} +\sqrt{57} =0: No Solution for Z

z

+

57

=0:NoSolutionforZ

\sqrt{z} -\sqrt{57} =0: z=57

z

57

=0:z=57

Your answer will be z=57

Answer:

Explanation:


(√(z) +√(22))(√(z) -√(22))=35

Subtract both sides from 35


(√(z)+√(22) (√(z) -√(22))-35=35-35

Simplify:


(√(z))^(2) -57=0

Factor
(√(z))^(2) -57: (√(z)+√(57)) (√(z)-√(57))=0


√(z) +√(57)=0 or √(z) -√(57)=0


√(z) +√(57) =0: No Solution for Z


√(z) -√(57) =0: z=57

Your answer will be z=57

and No solution
