Question

завести до стандартного вигляду многочлени 5x²-(8x²-2x-(3x-4x²))​

Answer 1

Объяснение:

$5x {}^{2} - (8x {}^{2} - 2x - (3x - 4x {}^{2} )) = 5x {}^{2} - (8x {}^{2} - 2x - 3x + 4x {}^{2} ) = 5x {}^{2} - (8x {}^{2} - 5x + 4x {}^{2} ) = 5x {}^{2} - (12x {}^{2} - 5x) = 5x {}^{2} - 12x {}^{2} + 5x = - 7x {}^{2} + 5x$

Answer 2

5х^2 - (8х^2 - 2х - (3х - 4х^2)) = 5х^2 - (8х^2 - 2х - 3х + 4х^2) = 5х^2 - (8х^2 - 5х + 4х^2) = 5х^2 - (12х^2 - 5х) = 5х^2 - 12х^2 + 5х = -7х^2 + 5х
