square root of (x+2)^2 = x+2
square root of 4 = 2
so equation will now be x+2 =2
Answer:
( x + 2 ) = 2
Step-by-step explanation:
Theo started to solve the quadratic equation
( x+2 )² - 9 = -5
He added 9 to both sides
( x + 2 ) ² -9 + 9 = - 5 + 9
( x + 2 )² = 4
Now he took the square root of each side
[tex]\sqrt{(x+2)^{2} } = \sqrt{4}[/tex]
[tex]\sqrt{(x+2)^{2} } =\sqrt{2^{2} }[/tex]
( x + 2 ) = 2
Therefore, resulting equation will be ( x + 2 ) = 2
