नाइन एक्स स्क्वायर प्लस टू एक्स प्लस 4 इज इक्वल टू जीरो है have real root no real root or real and districted root​

Answer 1

Step-by-step explanation:

9x²+2x+4=0

comparing equation with ax²+bx+c=0 we get

a=9 , b= 2, c=4

We know that -

D = b²-4ac

D = 2²-4×9×4

D = 4-144

D = -140

since D < 0

So the given equation has no real root.
