Answer 2

Answer:

-12

Step-by-step explanation:

Given: p=1, q=4, r=2

$12p(p-r)$

Plugin the value we get,

$=12*(1)(1-2)\\\\=12(1)(-1)\\\\= -12$

When different signs are multiplied answer will be negative, Here 1 and -1 are being multiplied that results in -1.

And when -1 is multiplied with 12 it gives -12.
