Answer:
[tex]X=3[/tex]
Step-by-step explanation:
[tex](x+3)^{2} -1=35[/tex]
The first you want to add the one to the other side
so it should be [tex](X+3)^{2} =36\\[/tex]
Then you’ll want to square root both sides which will look like:
[tex]\sqrt{(x+3)^2} = \sqrt{36\\[/tex]
Which simplified looks like:
[tex]X+3=6[/tex]
From there you should be able to deduced that:
[tex]X=3[/tex]
