please please please please help! really easy question but I'm stuck!

I am sooooo stuck on this question in my maths homework! I know it's a really easy one probably but I can't seem to do it! It's about factorising,
I don't know where the squared key on the p.c. is so I am going to put squared after the x to represent x squared

xsquared - 11x - 42

I know because of the x squared it has to be two sets of brackets each with x in the front and it has to be two numbers that add to make -11 and times to make -42 I THINK

please please please please please please please please please please help me!

Welcome to PF!
1. Cool down a bit, and answer first:
What do you need to know in order to factorize a polynomial?
 
? I'm only in year 9! but I am going to delete this thread cos my dad just saved me! phew! :blushing:
 
That was nice of him!
 
yeah, sorry for wasting your time
 
No problem!
You might compare my answer with your Dad's:
[tex]x^{2}-11x-42=(x-14)(x+3)[/tex]
