Question

Add the coefficients of the expression, -2x+3y-10.
​

Answer 1

Answer:

y2+3y−10

Factor the expression by grouping. First, the expression needs to be rewritten as y

2

+ay+by−10. To find a and b, set up a system to be solved.

a+b=3

ab=1(−10)=−10

Since ab is negative, a and b have the opposite signs. Since a+b is positive, the positive number has greater absolute value than the negative. List all such integer pairs that give product −10.

−1,10

−2,5

Answer 2

Answer:

Add the coefficients of the expression, -2x+3y-10.

Step-by-step explanation:

-2x+3y-10=0

-2x+3y=10

-2(-2)+3(2)=10

4+6=10

10=10
