I need help what do I write I don’t want to fail :(

a) There are 4 terms.

b) 2 of them are negative

explanation:

Let's simplify step-by-step.

−3x^2+2y^2+5xy−2y+5x^2−3y^2

=−3x^2+2y^2+5xy+−2y+5x^2+−3y^2

Combine Like Terms:

=−3x^2+2y^2+5xy+−2y+5x^2+−3y^2

=(−3x2+5x^2)+(5xy)+(2y^2+−3y^2)+(−2y)

=2x^2+5xy+−y^2+−2y

=2x^2+5xy−y^2−2y

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
