сколько корней имеет уравнение x⁴+8х³+23х²+32х+16=0?​

Answer 1

${x}^{4} + {8x}^{3} + {23x}^{2} + 32x + 16 = 0 \ (x + 1)({x}^{3} + {7x}^{2} + 16x + 16) = 0 \ (x + 1)(x + 4)({x}^{2} + 3x + 4) = 0 \ x + 1 = 0 \ x + 4 = 0 \ {x}^{2} + 3x + 4 = 0 \ x_1 = - 4 \ x_2 = - 1 \ OTBET: x_1 = - 4; : : : x_2 = - 1$
