Question

evaluate. :(3x+4y)(5x-y)​

Answer 1

Answer:

$\large \green{ \sf \: ANSWER}$

$\sf \: (3x + 4y)(5x - y) \: \: \: \: \: \: \: \: \: \\ = \sf \: 3x(5x - y) + 4y(5x - y)$

$\sf \: = 15 {x}^{2} - 3xy + 20xy - 4 {y}^{2}$

$\sf \: = 15 {x}^{2} + 17xy - 4 {y}^{2}$

Answer 2

Answer:

15x² + 17xy - 4y²

Step-by-step explanation:

Solution:

$\implies$ $\sf{(3x+4y)(5x-y) }$

$\implies$ $\sf{3x(5x-y) + 4y(5x-y) }$

$\implies$ $\sf{ 15x^2 - 3xy + 20xy -4y^2}$

$\therefore$ $\boxed{\sf{15x^2 + 17xy - 4y^2 }}$
