Question

$(4x + y)(7x - 6y)$
​

Answer 1

Answer:

$(4x + y)(7x - 6y) \\ = 4x(7x - 6y) + y(7x - 6y)$

$= 28 {x}^{2} - 24xy + 28xy - 6 {y}^{2} \\ = 28 {x}^{2} - 4xy - 6 {y}^{2}$

Answer 2

$\huge \bf{ \pink{Solution}}$

$\bf(4x + y)(7x - 6y)$

$\bf = 4x(7x - 6y) + y(7x - 6y)$

$\bf= 28 {x}^{2} - 24xy + 28xy - 6 {y}^{2}$

$\bf= 28 {x}^{2} - 4xy - 6 {y}^{2}$
