Maths algebraic question ​

Answer 1

Step-by-step explanation:

(5x - 3y) (x - 7y) 5x square - 35xy - 3xy + 21y square. 5x square - 38xy + 21y square. (x + 3y) (3x - 4y) 3x square - 4xy + 9xy - 12y square. 3x square + 5xy - 12y square. 5x square - 38xy + 21y square - (3x square + 5xy - 12y square) =2x square - 43xy + 33y square... (ANSWER) GOT IT...

Answer 2

Answer:

Step-by-step explanation:

(5x-3y)(x-7y)-(x+3y)(3x-4y)

5x(x-7y)-3(x-7y)-(x(3x-4y)+3y(3x-4y)

$5x^{2}$-35xy-3x+21y-($3x^{2}$-4xy)+9xy-$12x^{2}$

$5x^{2}$-35xy-3x+21y-$3x^{2}$+4xy+9xy-$12x^{2}$

$-10x^{2}$-22xy-3x+21y
