Question

State whether the following quadratic equations have two distinct real roots. Justify your answer,x²-3x+4=0​

Answer 1

Answer:

No it has no real roots

Step-by-step explanation:

We have, x^2 - 3x + 4 = 0

On comparing the above equation with ax^2+bx+c = 0

We get, a = 1 , b = -3 , c = 4

Now, D = b^2 - 4ac

= (-3)^2 - 4(1)(4)

= 9 - 16

D = -7

Since, D < 0

Therefore the given equation have no real roots .
