Объяснение:
3x^2-4x-5x^2-3+2x-1= -2x^2-2x-4
P(x) = P1(x) - P2(x) + P3(x)P1(x) = 3x² - 4x P2(x) = 5x² + 3P3(x) = 2x - 1
P(x) = P1(x) - P2(x) + P3(x) = (3x² - 4x) - (5x² + 3) + (2x - 1) = 3x² - 4x - 5x² - 3 + 2x - 1 = 3x² - 5x² - 4x + 2x - 3 - 1 = -2x² - 2x - 4 = -2(x² + x + 2)

Объяснение:
3x^2-4x-5x^2-3+2x-1= -2x^2-2x-4
P(x) = P1(x) - P2(x) + P3(x)
P1(x) = 3x² - 4x
P2(x) = 5x² + 3
P3(x) = 2x - 1
P(x) = P1(x) - P2(x) + P3(x) = (3x² - 4x) - (5x² + 3) + (2x - 1) = 3x² - 4x - 5x² - 3 + 2x - 1 = 3x² - 5x² - 4x + 2x - 3 - 1 = -2x² - 2x - 4 = -2(x² + x + 2)
