For -4+2, plot -4, then move to the right 2 spaces. You should land on -2.
For -4+(-2), plot -4 then move the left 2 spaces. You should land on -6.

bear in mind that, though the square has two valid roots, one negative and one positive, the hypotenuse is just a radius distance, and therefore is never negative.
Annual premium = 30 * 28.23 = $846.90
The way to write in the simplest form is to add all like terms.
-3x^2 + 2y^2 + 5xy - 2y + 5x^2 - 3y^2
2x^2 + 2y^2 + 5xy - 2y - 3y^2
2x^2 - y^2 + 5xy - 2y
There is 4 terms in the simplified expression.
Out of those 4 terms, 2 terms are negative.
