Question

(2x+3y+5)(2x+3y-5)solve this problem
​

Answer 1

$(2 x + 3y + 5)(2x + 3y - 5)$

$2x(2x + 3y - 5) + 3y(2x + 3y -5) \\ + 5(2x + 3y - 5)$

${4x}^{2} + 6xy - 10x +6yx + {9x}^{2} - \\ 15y + 10x + 15y - 25$

${4x}^{2} + 6xy + 6yx -10x + 10x + \\ {9x}^{2} - 15y + 15 - 25$

${4x}^{2} + 12xy + {9x}^{2} - 25$

Therefore 4x2 + 12xy + 9x2 - 25 is the answer.
