Question

if alpha,beta are the roots of the quadratic equation x2-b(x+1)=0,then (alpha+1)(beta+1)=?

Answer 1

Answer:

Your Answer is below....

Step-by-step explanation:

Let a and b be the roots of the quadratic equation,x²+x+1=0

We have,

x²+x+1=0

To find: 1/a + 1/b

__________________________________________________

★Some Rules of Polynomial

•Sum of Roots: -x coefficient/x²coefficient

•Product of Roots: constant term/x²coefficient

__________________________________________________

Here,

Sum of Roots:

a+b= -1

Product of Roots:

ab= 1

Now,

1/a +1/b

→ (a+b)/ab

→ (-1)/1

→ -1
