Question

X²-3=x
The value of a,b,c

Answer 1

Answer:

If x

2

+3x+3=0 and ax

2

+bx+1=0 & a,b ϵ Q have

a common root then volume (3a+b) is equal to

→ Let p,q be the common root between x

2

+3x+3=0

and ax

2

+bx+1=0

we know from properties of quadratic equation that

→ sum of roots , p+q=

a

−b

=−3

∴b=3a

→ product of root ,pq=

a

c

=

a

1

=3

∴a=1/3

∴b=3×

3

1

=1

∴ volume of 3a+b=3×

3

1

+1

3a+b=2

please mark as brainliest please

Answer 2

We can write
x^2-x-3=0
So a=1, b=-1 and c=-3
