ohh srry
mxddi3:
ok so do you know what the FOIL method is?
imbadatmath:
yea but i dont remember exactly i heard about it though
mxddi3:
so it's like
F: first terms
O:outer terms
I: inner terms
L: last terms.
so if we have (3x+8)(x+6) then we need to multiply the first term of each set.
this is going to be 3x(x)
do you know what that equals?
imbadatmath:
3x²

imbadatmath:
48
mxddi3:
woah mb. what is 3x(6)
imbadatmath:
18x
mxddi3:
yes,and you already did the outer terms which was 48, so now what is 8(x)
imbadatmath:
8x

Okay
mxddi3:
so you have \[3x^2 + 18x+ 48+ 8x\]
now, combine like terms
what do you get?
imbadatmath:
x⁴
mxddi3:
no. okay so the ONLY things in this equation that we can combine is the 18x and 8x. this is because the 3x squared has a square sign but the 18x and 8x do not.
do you follow?
imbadatmath:
yes

mxddi3:
so what is 18x+8x
imbadatmath:
26x
mxddi3:
good job. now you are left with
\[3x^2 + 26x+48\]
mxddi3:
that's your trinomial
imbadatmath:
thank u
