2xy means '2' multiplied to 'x' multiplied to 'y'.
In algebra the multiplication sign is NEVER shown.
Since 2xy is a factor of 2x2y, it is automatically the GCF.
2xy + 6xy = 8xy
(x + 4y)(x - 6y)
The greatest common factor of 4xy and -6xy is 2xy. To find the greatest common factor, we first factor out the numbers 4 and -6 to get 2(2xy) and -2(3xy). The greatest common factor is the highest common factor that divides both terms evenly, which in this case is 2xy.
√18xy = √(9*2xy) = √9*√2xy = 3*√(2xy)
The three terms are: -3xy2, 2xy and -4y3
4xy - 2xy
To simplify the expression (8x^2y + 2xy^2), you can factor out the common terms. The greatest common factor is (2xy), so the expression can be rewritten as (2xy(4x + y)). Thus, the simplified form is (2xy(4x + y)).
(2xy-4x)+ (8y-16)=2xy-4x+8y-16, which factors as 2(x+4)(y-2)
3xy and 2xy. You can see that 3xy and 2xy have something in common with each other. They both have xy and the end of them. Hope this helped.
What is : 5xy- x2t + 2xy + 3x2t
(x-y)2 is a square so (x-y)2 >= 0 expanding, x2 - 2xy + y2 >= 0 so x2 + y2 >= 2xy or 2xy <= x2 + y2
