Question

if x,B are zeroes of the polynomial 9x^-5x-4, then 1/x+1/B=​

Answer 1

Answer:

$x \: ,b \: are \: zeroes \: of \: polynomial p(x)=9x²-5x - 4 \\ </p><p>therefore, \: sum \: of \: zeroes, \: x + b = \frac{5}{9} \\ </p><p>Product \: of \: zeroes, \: xb = - \frac{4}{9} \\ </p><p>To find: \frac{1}{x} + \frac{1}{b} \\ = \frac{b +x }{xb} \\ = \frac{5}{9} \div ( - \frac{4}{9} ) \\ = - \frac{5}{4}$
