If what are both negative?
You have to multiply both sides (the entire thing) by -1. It's complicated, so save it for when you have a trinomial or less on both sides.
A binomial has two terms, while a trinomial has 3 terms. So both terms of the binomial will multiply each term of the trinomial (distribution property). After the multiplication you'll have 6 terms. Look for like terms, if there are, combine them.
Yes, as long as the negative slopes are both equal.
positive
Not necessarily. They could both be positive.
One positive one negative (apex)
-- If the last term of the trinomial ... the one that's just a number with no 'x' ... is positive, then both factors have the same sign as the middle term of the trinomial. -- If the last term is negative, then the factors have different signs. If this was never pointed out in class, well, it should have been.

If both numbers are positive, simply add them as you learned in 4th grade. If both numbers are negative,simply add them but add a minus to the answer. If one is positive and the other negative, ignoring the signs,subtract the smaller from the larger and add the sign of the larger to your answer.
The sum of two numbers depends on their signs and relative magnitudes.Both positive: sum positive Both zero: sum zero Both negative: sum negative Larger magnitude positive, smaller magnitude negative: sum positive Larger magnitude negative, smaller magnitude positive: sum negative Same magnitude, one positive and other negative: sum zero.

This is related to the fact that the square of both a positive and a negative number is always positive. The last term is simply the square of the second term, in the original binomial.
-- If they both start out with the same sign (both negative or both positive), then do this: . . . . . add their two values . . . . . the answer has the same sign as the two original integers. -- If they start out with opposite signs (one negative and one positive), then do this: . . . . . forget about the signs . . . . . find their difference (subtract the smaller number from the larger one) . . . . . give it the sign of whichever original integer was the larger number.
