Question

fun question

Answer 1

?

Answer 2

solve for \(y,\ \ y\in \mathbb{R}\)

\(\large \color{black}{\begin{align} |y+k|=-4\hspace{.33em}\\~\\

\end{align}}\)

where roots of \(2x^2-(5k+4)+7=0\) are equal in magnitude and opposite in sign.

Answer 3

how is this fun? ;~;

Answer 4

is there a "x" missing in the middle term of given quadratic equation ?

Answer 5

\[2x^2-(5k+4)\color{red}{x}+7=0\]

Answer 6

let me see ,wait

Answer 7

yes u r right x was missing

Answer 8

solve for \(y,\ \ y\in \mathbb{R}\)

\(\large \color{black}{\begin{align} |y+k|=-4\hspace{.33em}\\~\\

\end{align}}\)

where roots of \(2x^2-(5k+4)x+7=0\) are equal in magnitude and opposite in sign.

Answer 9

but how can absolute value be negative ?
