Question 1018622: hi! I'm Gracie, my class is going over chapter 8 in our text book. Chapter 8 is dealing with polynomials and factoring. chapter 8.6 is about factoring expressions. I don't understand how to factor this expression though, can you help me?
3x^2 + 16x + 3
thanks!
p.s. I wrote the wrong email before Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! 3x^2 + 16x + 3
This doesn't factor. (3x+1)(x+3) gives the largest x value which is only 10x.
3x^2+16x+13 does factor into (3x+13)(x+1)
quadratic formula
x=(1/6)*(-16+/- sqrt (256-36)); sqrt 220=14.83, so no integer roots. (numerically about -.23 and -5.14) ,
