Question

If A=x2y3−3xy2+5x3y, B=−7xy2−2x3y−3x2y3 and, C=−x3y+4xy2+7x2y3, determine the expression obtained by simplifying.

A+(B+C)

Answer 1

Answer:

If A=x2y3−3xy2+5x3y, B=−7xy2−2x3y−3x2y3 and, C=−x3y+4xy2+7x2y3

Answer 2

Answer:

5x2y3 + 2x3y - 6xy2

Step-by-step explanation:

Step 1 - A+(B+C) = −7xy2 − 2x3y − 3x2y3 - x3y + 4xy2 + 7x2y3

                           = 4x2y3 - 3x3y - 3xy2

Step 2 - A+ 4x2y3 - 3x3y - 3xy2 = x2y3−3xy2+5x3y + 4x2y3 - 3x3y - 3xy2

                                                     = 5x2y3 + 2x3y - 6xy2
