Question

(4x - y) (x - 3y) - (x - 2y) (2x - y)​

Answer 1

Step-by-step explanation:

$(4x - y)(x - 3y) - (x - 2y)(2x - y) \\ \\ (4 {x}^{2} - 12xy - xy + 3 {y}^{2}) - (2 {x}^{2} - xy - 4xy + 2 {y}^{2} ) \\ \\ 4 {x}^{2} - 12xy - xy + 3 {y }^{2} - 2 {x}^{2} + xy + 4xy - 2 {y}^{2} \\ \\ 2 {x}^{2} - 8xy + {y}^{2}$
