The value of the polynomial expression D - C is; 4·y² - y - 10
The steps used to find the value of the difference between the polynomials D and C is presented as follows;
The polynomial expressions can be presented as follows;
C = 3·y² + 4·y + 4
D = -7·y² + 3·y - 6
Therefore; D - C = 7·y² + 3·y - 6 - (3·y² + 4·y + 4)
D - C = 7·y² - 3·y² + 3·y - 4·y - 6 - 4
7·y² - 3·y² + 3·y - 4·y - 6 - 4 = 4·y² - y - 10
D - C = 4·y² - y - 10
The question obtained from a similar question found through search can be presented as follows;
C = 3·y² + 4·y + 4
D = -7·y² + 3·y - 6
D - C = ___
