Question

Simplify the following expressions: (2x+7y) (x-3y) – (9x+4) (3x-2) proper solution​

Answer 1

Step-by-step explanation:

2x(x-3y)+7y(x-3y)-((9x(3x-2)+4(3x-2)

2x²-6xy+7xy-21y²-((27x²-18x+12x-8)

2x²+xy-21y²-27x²+6x+8

-25x²+xy-21y²36x+8 is the answer

Answer 2

Answer:

29x^2+21y^2-30x-8

Step-by-step explanation:

x(2x+7y)-3y(2x+7y) -3x(9x+4) -2(9x+4)

2x^2+7xy-6xy-21y^2-27x^2-12x-18x-8

2x^2+xy-21y^2-27x^2-30x-8

25x^2+xy-21y^2-30x-8
