Question

if a,b are zeroes of polynomial p(x)=2x²-7x+3, then find the value of 1/a + 1/B​

Answer 1

Answer:

$a,b \: are \: zeroes \: of \: polynomial \: p(x)=2x²-7x+3 \\ </p><p>therefore, s \: um \: of \: zeroes, \: a + b = 7/2 \\ </p><p>Product \: of \: zeroes, ab = 3/2 \\ </p><p>To find: \frac{1 }{a} + \frac{1}{b} \\ = \frac{b + a}{ab} \\ = \frac{7}{2} \div \frac{3}{2} \\ = \frac{7}{3}$
