Question

8х²-10х+2=0 решите пжлст

Answer 1

$8 x^{2} -10x+2=0$

$D = b^{2} -4ac=100-4*8*2=100-64=36$

$x_{1} = frac{-b+ sqrt{D} }{2a} = frac{10+ sqrt{36} }{2*8} = frac{10+6}{16} = frac{16}{16} =1$

$x_{2} = frac{-b- sqrt{D} }{2a} = frac{10- sqrt{36} }{2*8} = frac{10-6}{16} = frac{4}{16} = frac{1}{4}$

Ответ: $x_{1} =1; x_{2} = frac{1}{4}$

Answer 2

Eug3nz, у тебя ошибка
