What is the difference of the two polynomials?
(7y2 + 6xy) - (-2xy + 3)

  7y^2 +8xy -3

Step-by-step explanation:

Distribute the minus sign and combine like terms.

  = 7y^2 +6xy +2xy -3

  = 7y^2 +8xy -3

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
