hello from mrbilldoesmath!

answer:

1.     x(12-3x)

2.   240 ( sqrt(1/12) + x ) (sqrt(1/12)   - x)

discussion:

1.  

12x - 3x^2   =                       => factor x from each term

x(12-3x)

2.

20 - 240x^2 =                   => factor 240 from each term

240   ( 20/240 - x^2)=       => 20/240 = 2/24 = 1/12

240 ( 1/12   - x^2) =             => as a^2 - b^2 = (a+b)(a-b)

240 ( sqrt(1/12) + x ) (sqrt(1/12)   - x)

you,
