Answer:

1) (x+4)2 =49

Explanation:

To find the equivalent equation we make use of completing the squares. To do this we first write

[tex]x^2+8x-33=0[/tex]

adding 33 to both sides gives

[tex]x^2+8x=33[/tex]

We complete the square by adding 16 to both sides

[tex]x^2+8x+16=33+16[/tex]

which gives

[tex](x+4)^2=49[/tex]

which is choice 1.
