Question

if a and b are the roots of the quadratic equation 4xsquar +3x+7=0 then what is the value of 1\a+1/b?​

Answer 1

Answer:

$Given: α,β are \: zeroes \: of \: them \: polynomial 4x2+3x+7$

To \: find \: the \: value \: of α1+β1 \\

From the given quadratic equation,

α+β=−43 and αβ=47

Therefore, 

α1+β1=αβα+β

=47−43=−73

⇒α1+β1=−73
