Question

check whether roots of the polynomial 3x²_x+4=0 are real or not​

Answer 1

Step-by-step explanation:

3x²-x+4=0

b²-4ac

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

(-1²)-4(3)(4)

1-48

-47

b²-4ac<0 ( smaller than zero)

no real roots

Answer 2

Here,

$a = 3 \\ b = - 1 \\ c = 4$

So,

${b}^{2} - 4ac \\ = {( - 1)}^{2} - 4 \times 3 \times 4 \\ = 1 - 48 \\ = - 47$

Since,

${b}^{2} - 4ac < 0$

So there are no real roots.
