Question

If zeroes of
$f(x) = 2x ^{2} + 5x + k$
are the reciprocal of each other, then value of k is

Answer 1

⭐⭐Hello friend..Ur answer is here⤵⤵

⚫ 2x^2+5x+k

➡ let the zeroes are a and 1/a

➡a×1/a=k/2

➡ 1=k/2

➡ k=2

I HOPE IT IS HELPFUL TO YOU ☺

Answer 2

solution.


$let \: the \: zeroes \: be \: x \: and \: \frac{1}{x}$
then product of zeroes= c/a

=>
$\frac{1}{x} \times x = \frac{k}{2} \\ \\ = > 1 \: = \frac{k}{2 } \\ = > k = 2$
