Question

if alpha and beta are the zeros of the given quadratic polynomial P of X equal to 5 x square - 7 x + 1 find the value of one by Alpha Plus One by beta.

Answer 1

Heya !!!


P(X) => 5X² -7X + 1


Here,


A = 5 , B = -7 and C = 1



Sum of zeroes = -B/A


Alpha + Beta = -(-7)/5



Alpha + Beta = 7/5



and,


Product of zeroes = C/A


Alpha × Beta = 1/5




Sum of the zeroes of Quadratic polynomial whose zeroes are 1/Alpha and 1/Beta


Sum of zeroes = 1/ Alpha + 1/Beta



=> 1 × Beta + 1 × Alpha / Alpha × Beta



=> Beta + Alpha / Alpha Beta


=> 7/5 / 1/5



=> 7/1


=> 7
