hi this is my question:
3x^2+4+x(x-1)
for this i know i would do
3x^2+4
but after that im kinda stuck!
would i do
3x^2+4 2x-x = 3x^2+x+4??
could you help please?
Hi andyboy179,
you need to know how to multiply out the terms of x(x-1)
You do it the exact same way as 3(3-1)=3(2)=6
3(3-1)=3(3)+3(-1)=9-3=6
Or 5(5-1)=5(4)=20
5(5-1)=5(5)+5(-1)=25-5=20
You just multiply the x by both terms inside the brackets
Now combine that with
Can you continue from there?
