Question

8.if α and β are the zeroes of the given quadratic polynomial p(x)=5x^2
-7x+1, find the value of

1/α +1/β.

Answer 1

here is your answer by Sujeet,

Given that,
5x²-7x+1

Sum of zeroes=-b/a=-(-7)/5=7/5
product of zeroes=c/a=1/5

Then,
value of,
1/a+1/b
=}a+b/an
=}7/5 / 1/5
={7


value 7

that's all,,,

any problems ask me..........
