X^2 - 4x + 4 = 0
(x - 2)^2 = 0 - Factor left side
x - 2 = 0 - Square root each side
x = 2 - add 2 to each side

Is there any multiple choice answers that go with this?

If not, I got X=2

We need to cross multiply.

$\frac{a}{b} = \frac{c}{d}$

$= \frac{a}{b} \times bd= \frac{c}{d} \times bd$

ad=bc

So your question is:
$\frac{d}{1.2}=6$

This can also be written as:
$\frac{d}{1.2} = \frac{6}{1}$

So if we cross multiply, we will get

$d \times 1 = 1.2 \times 6$

d= 7.2
