Question

БЫСТРО!!!
1)-x^2-2x+24=0
2)-x^2-5x+6=0

Answer 1

$D=b^{2} -4ac=(-2)^{2} -4*(-1)*24=4+96=100$
$sqrt{D} =10$
$x_{1} = frac{2+10}{2} = frac{12}{-2} =- 6$
$x_{2} = frac{2-10}{2} = frac{-8}{-2} =4$
Ответ: - 6; 4 
$D=b^{2} - 4ac=(-5)^{2} -4*(-1)*6=[tex]25+24=49$
$sqrt{D} =7$
$x_{1}= frac{5+7}{-2} = frac{12}{-2} =-6$
$x_{2} = frac{5-7}{2} = frac{-2}{-2} =1$
Ответ: - 6;1.
