Question

if alpha and beta are the zeroes of 1x^2 - 1x -4 . find 1/alpha+ 1/beta - alpha* beta​

Answer 1

Answer:

Given ∝andβ are the roots of

the quad ration equation

f(x)=x

2

−p(A+1)−c

=x

2

−px−(p+c)

Comparing with ax

2

+bx+c, we have

a=1b=−pc=−(p+c)

∝+β=

a

−b

=−

1

(−p)

∝β=

a

c

=−(p+c)

∵(∝+1)(β+1)

=∝β+∝+β+1

=−p−c+p+1

=1−c

∵(∝+1)(β+1)=1−c

solution
