Question

if alpha and bite are the zeros of x2+5x+4 then 1/alpha+1/bita=​

Answer 1

Answer:

1/alpha+1/bita =alpha+bite/alpha*bite

so, alpha+ bite=-5

alpha* bite =4

so, alpha+ bite/alpha* bite=-5/4

Answer 2

x² + 5x + 4 = 0.

The total of the zeros = - 5/1

= (-5)

The product of the zeros = 4/1

= 4.

1/alpha + 1/bita

= (alpha + bita) / alpha×bita

= -5/4.
