Question

X^2-400x-480000=0 solve for x

Answer 1

$\huge \boxed{hello \: friends}$

$\underline \bold{Given}$

$\bold{x {}^{2} - 400x - 480000 = 0 }$

$\underline \bold{solution}$

$\green{Compare \: the \: given \: equation \: with}$

$\bold {ax {}^{2} + bx + c = 0}$

$\bold{a \: = 1 \: \: b = - 400 \: \: \: \: c = - 480000}$

$\bf{b {}^{2} - 4ac \: = ( - 400) {}^{2} - 4 \times 1 \times - 480000 }$
$\bold{ b {}^{2} - 4ac = >160000 - 480004 }$
$\bf{b {}^{2} - 4ac = - 320004}$

$\red{Here....}$

$\bold{b {}^{2} - 4ac \: < 0 }$

$\bold{Therefore \: the \: roots \: are \: not \: real}$

$\green{Hence}.....$

$\bold{We \: can \: not \: fine \: the \: value \: of \: x}$

$\huge \frak{Thanks}$
