I'm stuck on this, does anyone know the solution? The question is:
Calculate (2p - 4q) 2 when p= - 8 and q = - 3.​

-14 or -28

Step-by-step explanation:

2x-8=-16

4x-3=-12

-16-12=28

-16-(-12)=-14

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
