Split the second term 7x^2 - 8x - 12 into two terms
7x^2 + 6x - 14x - 12
Factor out common terms in the first two terms, then in the last two terms
x(7x + 6) - 2(7x + 6)
Factor out the common term; 7x + 6
<u>(7x + 6)(x - 2) </u>

Answer:
 Ben can type 510 words in 10 minutes.
Step-by-step explanation:
The relation between the number of words typed and the minutes is direcltly proportional, that is, with Ben type more minutes, he will end up typing more words.
Thus, we can use the rule of three:
words    |    minutes
  153      ---      3
     x       ---      10
  
Now, we can just cross multiply them:


Thus, Ben can type 510 words in 10 minutes.
 
        
                    
             
        
        
        
(3x+6)(2x^2), using the distributive property, equals 2x^2*3x+2x^2*6. We multiply the 2 with the coefficients and add a power of x if multiplied by x, getting 6x^3+12x^2
