Question

X²-2xy+y²=? x= -4,2; y=3 7 класс

Answer 1

Ответ:

51,84

Объяснение:

х²-2ху+у²=(х-у)²=(-7,2)²=51,84

Answer 2

To find the value of the expression x² - 2xy + y² when x = -4 and y = 3, we substitute these values into the expression:

(-4)² - 2(-4)(3) + 3²

Simplifying the expression:

16 + 24 + 9

Combine like terms:

49

Therefore, when x = -4 and y = 3, the expression x² - 2xy + y² equals 49.
