Answers
Given : T-shirt costs (x² -xy-y²)
a sweater costs (2x² + 8xy - 2y²)
a jeans cost `(x² -3xy+4y²)
After buying these items Mohit paid `(2x+y)²
To Find : Amount Mohit receive from the cashier
Solution:
T-shirt costs (x² -xy-y²)
a sweater costs (2x² + 8xy - 2y²)
a jeans cost `(x² -3xy+4y²)
Total Cost = (x² -xy-y²) + (2x² + 8xy - 2y²) + `(x² -3xy+4y²)
= (4x² + 4xy + y²)
Mohit paid (2x + y)²
= 4x² + 4xy + y²
Total cost and what mohit paid are same
Hence Mohit will not receive any amount from the cashier
or say Zero Amount
