Simplify – 2(7x – 3)
ANTONII [103]

All you need to do here is multiply the outside number by both 7x and -3.

When done correctly it should look like this:

-14x+6

Thats the answer.

7 times 2 gives you 14 but when multiplying mixed signs it turns negative so it would be -14.

negative 3 times negative 2 gives you 6. Both signs are negative, and you would suppose it would turn into a negative but thats only true when both signs are mixed. Both the 3 and the 2 are negative, making the signs the samez giving you positive

How to factorize the following expression?<br>pqr + pr + q + 1​
Sveta_85 [38]
<h3>Answer:  (pr + 1)(q + 1)</h3>

===============================================

Work Shown:

Use the factor by grouping method to get the following.

pqr + pr + q + 1​

(pqr + pr) + (q + 1​)

pr(q + 1) + 1(q + 1)

(pr + 1)(q + 1)

We can use the FOIL rule, distribution, or the box method to expand out  (pr+1)(q+1) to get the original expression again. This helps confirm the answer.
