Question

X^2+2xy+y^2-2x-2y+5, если = x + y = 3?

Answer 1

Ответ:

Объяснение:

X²+2xy+y²-2x-2y+5=(х+у)²-2(х+у)+5=3²-2·3+5=9-6+5=8

Answer 2

This appears to be a mathematical expression. If you're looking for the value of the expression $x^2 + 2xy + y^2 - 2x - 2y + 5$ when $x + y = 3$, you can solve it as follows:

1. Substitute $x + y = 3$ into the expression: $x^2 + 2xy + y^2 - 2x - 2y + 5 = (x + y)^2 - 2(x + y) + 5$

2. Now, plug in the value of $x + y = 3$: $3^2 - 2(3) + 5 = 9 - 6 + 5 = 8$

So, the value of the expression $x^2 + 2xy + y^2 - 2x - 2y + 5$ when $x + y = 3$ is 8.
