Question

what is the answer for -2p-(-12p)​

Answer 1

Answer:

The question is -2p-(-12p)

When - sign comes in front of a bracket, the sign of the number inside the bracket changes,

So,

-2p + 12p

Here p is common, lets take it out:-

p ( -2 + 12)

p (10) = 0

p = 10

Answer 2

• $\sf\:-2p-(-12p)$

‎

$\large\sf\underline{Answer}$

• We can add or subtract these terms since they are like terms .

$\sf\:-2p-(-12p)$

$\sf➞\:-2p+12p$

$\sf➞\:10p$

$\large\sf\underline{Know\:more}$

• "Like terms" are terms that contain the same variables raised to the same power.h

Important :

We can only add or subtract like terms.

Why ?

Think of it like this. On a table we have 4 pencils and 2 books. We cannot add the 4 pencils to the 2 books - they are not the same kind of object.

Similarly with algebra, we can only add (or subtract) similar "objects", or those with the same letter raised to the same power.
