how to rewite 10x + 4 - 3 + 8x + 2, x2 + 4 + 2(x - 1) + 3 + 2x, and 3x2 - 48x?

I'll show you 1, try to do the other one by yourself. :))

I'm also assuming you meant. 

3x^2 - 48x

3x(x - 16)   # factor 3x from both sides

how to rewite 10x + 4 - 3 + 8x + 2, x2 + 4 + 2(x - 1) + 3 + 2x, and 3x2 - 48x?   

 

First, group terms of the same power    

 

10x + 8x + 4 – 3 + 2                18x + 3              3 • (6x + 1)  

 

x² + 4 + 2x + 2x – 2 + 3                                    x² + 4x + 5  

 

3x² – 48x                                                         3x • (x – 16)
