yes * * * * * No, it isn't. 2xy = 2 times x times y. Depending on which you mean: 2x2y = 2 times x times 2 times y = 4xy; OR 2x2y = 2 times x times x times y.

8-x2y 8-2xy 2xy-8

2xy substitute 3 for y and 5 for x 2(5)(3) = 30

it means two times x times y.

You can expand (x + y)2 into x2 + 2xy + y2

yes * * * * * No, it isn't. 2xy = 2 times x times y. Depending on which you mean: 2x2y = 2 times x times 2 times y = 4xy; OR 2x2y = 2 times x times x times y.

(x + 4y)(x - 6y)

8-x2y 8-2xy 2xy-8

15xy-2xy-7x+x=13xy-6x

it would equal 2xy

X²+2xy+y²

(x-y)2 is a square so (x-y)2 >= 0 expanding, x2 - 2xy + y2 >= 0 so x2 + y2 >= 2xy or 2xy <= x2 + y2

2xy*9 if x=3 and y = 2 2(3)(2)*9 12*9 108 You substitute x and y for their equivalent (3 and 2) then simply multiply 2*x*y, then multiply the answer of that by 9.

2xy substitute 3 for y and 5 for x 2(5)(3) = 30
