Question

Find the roots of the Quadratic equation x3 + 2x - 3 = 0.
​

Answer 1

Answer:

For equation ax

2

+bx+c=0

Roots are given as =

2a

−b±

b

2

−4ac

Now let us compare ax

2

+bx+c=0 with x

2

−2x+3=0 to find the values of a,b,c

After it we can directly put a,b,c into the formula to find the roots

By comparing a=1,b=−2,c=3

So roots =

2×1

−(−2)±

(−2)

2

−4(1)(3)

=

2

2±

4−12

=

2

2±

−8

=1±i

2

Hence the roots of the equation x

2

−2x+3=0 are imaginary
