Question

The sum of -7p²q² and 19p²q² ​

Answer 1

Given numbers are -7p²q² and 19p²q² ​

We have to add the two numbers

The addition can be done as shown

= -7p²q² + 19p²q²

Taking p²q² common

=p²q²( -7 + 19)

= 12p²q²

So, the summation of the two numbers, -7p²q² and 19p²q² ​ will be 12p²q²

Answer 2

Given that:-

$-7p^2q^2$ and $19p^2q^2$

As we have to simplify by adding both expressions

Therefore,

$=>-7p^2q^2+19p^2q^2$

Now, taking $p^2q^2$ as common,

$=>(-7+19)p^2q^2$

$=>12p^2q^2$

Hence, the sum of $-7p^2q^2$ and $19p^2q^2$ is $12p^2q^2$
