Answer:

x=±sqrt (33)

Step-by-step explanation:

y=(x+2)(x-2)

29=x^2-4. x^2=33, x=±sqrt (33)

Answer:

[tex]\sqrt{33}[/tex]

Step-by-step explanation:

y = (x+2) (x-2)

y =  [tex]x^{2}[/tex] +2x -2x-4

y =  [tex]x^{2}[/tex] - 4

29 = [tex]x^{2}[/tex] - 4

29 + 4 = [tex]x^{2}[/tex] -4 + 4

33 = [tex]x^{2}[/tex]

[tex]\sqrt{33}[/tex] = x

Hope this is clear and you can understand it. :)
