Question

From the product of ( x+ 2y –2 ) and ( x –2 ), subtract 2x^2 –3xy + 4y .

Answer 1

Answer:

$- {x}^{2} - 4x + 5xy - 8y + 4$

Step-by-step explanation:

$((x + 2y - 2)(x - 2)) - (2 {x}^{2} - 3xy + 4y) \\ = )( {x}^{2} - 4x + 2xy - 4y + 4) -( 2 {x}^{2} - 3xy + 4y) \\ = ) {x }^{2} - 4x + 2xy - 4y + 4 - 2 {x}^{2} + 3xy - 4y \\ = ) - {x}^{2} - 4x + 5xy - 8y + 4$
