Question

if alpha and beta are the zero of the polynomial 4x^2 + 3 X + 7 find the value of one by Alpha+ One by beta

Answer 1

Hey

Here is your answer,

4x^2 + 3x + 7=0

Sum of zeroes = -b/a
Alpha + beta= -3/4

Product of zeroes = c/a
Alpha x beta = 7/4

=1/alpha+1/beta
=alpha+beta/alpha x beta
=-3/4 / 7/4
=-3/4

Hope it helps you!
