Question

in the quadratic equation ax2 +bx +c=0,if a =0, then name the type of the equations so obtained. Plz help me with this answer ​

Answer 1

Answer:

quadratic equations I think so .......

Answer 2

Step-by-step explanation:

The given quadratic equation is 2x

2

+3x+4=0

Now, we are going to find roots of the given equation.

x=

(2)(2)

−3±

(3)

2

−4(2)(4)

x=

4

−3±

9−32

x=

4

−3±

−23

∴ x=

4

−3±

23

i

So, here 2x

2

+3x+4=0 will give complex roots.

It is given that ax

2

+bx+c=0 and 2x

2

+3x+4=0 have a common root.

So, ax

2

+bx+c=0 also ahve these complex pairs.

This means least value will be obtained at a=2,b=3 and c=4

∴ a:b:c=2:3:4
