Question

result obtain on subtracting product of 2x and (x-3y) from product of (5x+3y)and (2y+1)​

Answer 1

2x(x-3y) = 2x^2-6xy

(5x+3y)(2y+1) = 10xy+5x+6y^2+3y

10xy+5x+6y^2+3y - (2x^2-6xy) = 16xy + 5x + 6y^2 + 3y - 2x^2

:-)

Answer 2

Answer:

16xy+5x+6y^2+3y-2x^2

Step-by-step explanation:

multiply

2x (x-3y)=2x^2-6xy

(5x+3y)(2y+1)=5x (2y+1)+3y(2y+1)

=10xy+5x+6y^2+3y

10xy+5x+6y^2+3y+0

(+) (-) (-) (-) (-)

-6xy + 0+ 0 +0 +2x^2
