Simplify : (7x – 9y2)(2x2 – 3y) – (5x + 2y)(9x – 10y) - 2x(3x + 5y)

​

Answer 1

Step-by-step explanation:

(7x-9y2)•((2•(x2))-3y))-((5x+2y)•(9x-10y)))-2x•(3x+5y)

(7x-(9•(y2)•((2•(x2))-3y)-(5x+2y)•(9x-10y))-2x•(3x+5y)

(((7x-(9•(y2)))•(2x2-3y))-(5x+2y)•(9x-10y))-2x•(3x+5y)

(((7x-32y2)•(2x2-3y))-(5x+2y)•(9x-10y))-2x•(3x+5y)

((7x-9y2)•(2x2-3y)-(5x+2y)•(9x-10y))-2x•(3x+5y)

by cancelling the equation.

we get (((14x3 - 18x2y2 - 51x2 + xy + 27y3 + 20y2)))
