Question

• (i) (2x - Зу + 5) (2x - Зу - 5)​

Answer 1

$\large\fbox\red{Answer}$

$\sf\:(2x - Зу + 5) (2x - Зу - 5)$

$\sf⟹\:2x(2x - Зу - 5) -3y(2x - Зу - 5) +5(2x - Зу - 5)$

$\sf⟹\:4x^{2} - 6xу - 10x -6xy + 9у^{2}+ 15y + 10x - 15y - 25$

$\sf⟹\:4x^{2}+ 9у^{2}- 6xу-6xy- 10x+ 10x + 15y- 15y-25$

$\sf⟹\:4x^{2}+ 9у^{2}- 12xy -25$
