Factorising Quadratics

Shes not sure about what to do for the last one... x² + x - 56

I've showed you that one already. D:

What divisors of -56 add up to 1? or... what divisors of 56 have the difference 1.

Sorry! I read it just my brain isn't feeling up to maths this afternoon! Thank you! Sorry again <3

Much love for the help <3

8 and -7 multiply to -56

they also add up to 1

so (x+8)(x-7)

On to the next questions D:

 

x² - 16

 

x² - 49

 

x² - 144

 

x² -196

 

So for the first one I'm guessing its just (x+4)(x-4) right?

Or is it something else completely different? Aghh

Good lord there are more D:

 

Circle Theorems this time...

You're right about the first one. They're all difference's of two squares. The second would be (x-7)(x+7) and third (x-12)(x+12). 

I would help with the circle theorems but I suck at them as well ._.

These are easy...

I don't know how exactly to explain them in English though.

I wish I wasn't so stubborn about math. Seeing a couple of you have no issues with these equations looks like a super power to me.

When I see equations more complicated than than 4 steps and has a bunch of rules, my brain just shuts down.
