Question

СРОЧНО 50 БАЛЛОВ ЗАДАНИЕ НА КАРТИНКЕ

Answer 1

Ответ:

Объяснение:

M=4x⁵+x³y-5x²y²+4xy³-y⁶

N=-7x⁵+4x³y+5x²y²+y⁶

K=x⁵-2x³y-2x²y²+6xy³-2y⁶

M+N+K=4x⁵+x³y-5x²y²+4xy³-y⁶+(-7x⁵)+4x³y+5x²y²+y⁶+x⁵-2x³y-2x²y²+6xy³-2y⁶=-2x⁵+3x³y-2x²y²+10xy³-2y⁶

M-N+K=4x⁵+x³y-5x²y²+4xy³-y⁶-(-7x⁵+4x³y+5x²y²+y⁶)+x⁵-2x³y-2x²y²+6xy³-2y⁶=4x⁵+x³y-5x²y²+4xy³-y⁶+7x⁵-4x³y-5x²y²-y⁶+x⁵-2x³y-2x²y²+6xy³-2y⁶=12x⁵-5x³y-12x²y²+10xy³-4y⁶
