4x + 2y - (2x - 4y) + 13xy = 4x + 2y - 2x + 4y + 13xy = 2x + 6y + 13xy
x = 2 y = 3
2x + 6y + 13xy = 2 * 2 + 6 * 3 + 13 * 2 * 3 = 4 + 18 + 78 = 100
Значение данного многочлена 4x+2y−(2x−4y)+13xy равно 100 .

4x + 2y - (2x - 4y) + 13xy = 4x + 2y - 2x + 4y + 13xy = 2x + 6y + 13xy
x = 2 y = 3
2x + 6y + 13xy = 2 * 2 + 6 * 3 + 13 * 2 * 3 = 4 + 18 + 78 = 100
Значение данного многочлена 4x+2y−(2x−4y)+13xy равно 100 .
