Answer 1

Answer:

x=i√33−3,−i√33−3

hope this helps :)

Step-by-step explanation:

Subtract 5 from both sides of the equation.

(x+3)2=−28−

5 Subtract 5 from −28.

(x+3)2=−33

Take the square root of both sides of the equation to eliminate the exponent on the left side.

x+3=±√−33

Simplify the right side of the equation.

x+3=±i√33

The complete solution is the result of both the positive and negative portions of the solution.

x=i√33−3,− i√33 −3
