6x^{2}+19x+10
When we have a quadratic, ax^{2}+bx+c, we can factor by finding what two numbers when multiplied equal a*c and when added equal b.
In this case, find what two numbers when multiplied equal 60 and when added equal 19.
How about 15 and 4? 15*4=60 and 15+4=19.
6x^{2}+15x+4x+10
Now, group, factor out a common term, and finish.
Remember, what is inside the parentheses must be the same for it to work.
