Factoring ax^2 + bx +c
Continued
"Ok here is
the box we
are going to
use to factor
the problem
5x^2 + 11x +
2." "Here is
the trick."
"You need to
find a
combination
of numbers
that fit the
following."
Here
and
here.
You need to get
two numbers to
multiply to
equal the first
term. The
product goes
here.
Here
and
here.
You need to get two
numbers that multiply
to equal the last term.
After you have
numbers on all of
the black lines
follow the yellow
arrows for how to
fill in the boxes.
The two red boxes
should also add to
give you the last
term.
Now this might
all seem jolly
complicated but
if you click here
it will make more
sense.
This box should
end up with the
last term in it.
