Question

Silplify and find the value of the following:
1- (3x-2y) (2x+5y) at x=0, y=1.

Simplify
1- (a+b) (a²+b²-ab)
2- (x²+5) (y³+3)+6

Answer 1

Step-by-step explanation:

1. (3x-2y) (2x+5y)

=(3.0-2.1) (2.0+5.1)

=(0-2) (0+5)

=-10

Answer 2

Step-by-step explanation:

a(a ^2+b^2-ab) +b(a^2+b^2-ab)

(a^3+ BA^2 minus ab^2 ) +( b a square +b cube - ab^2 square )

a^3+ 2 b a square -2 a b square plus b cube
