a since 3 is positive and one is negative
I followed the numbers across, thinking to myself "this won't be
too hard to multiply, because they're all small numbers". And then
when I got to the zero, I burst out laughing ! It doesn't matter at all
what all the other numbers are. Once there's a zero in there, the whole
product will be <em>zero</em>, no matter what else gets multiplied along the way.
There could be millions and billions in there. You wouldn't need to do
any calculating at all. With zero as a factor, you know right away that
the product is zero.
So it's saying to
(5x^2 + 10x - 5) - (7x^2 + 4x - 9)
Collect the like terms
and regroup
(5x^2 - 7x^2) + (10x - 4x) + ( -5 + 9)
Simplify
-2x^2 + 6x + 4
Hope this helps :)
