Question

If y=29,find x

y=(x+2)(x-2)
Please show working

Answer 1

Answer:

x=±sqrt (33)

Step-by-step explanation:

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

29=x^2-4. x^2=33, x=±sqrt (33)

Answer 2

Answer:

$\sqrt{33}$

Step-by-step explanation:

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

y =  $x^{2}$ +2x -2x-4

y =  $x^{2}$ - 4

29 = $x^{2}$ - 4

29 + 4 = $x^{2}$ -4 + 4

33 = $x^{2}$

$\sqrt{33}$ = x

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