Question

The number of real roots of the equation 2
x^2 - 7x + 12 = 0
are ____ ?

Answer 1

Explanation:

Its easy one

So value of eqn is 3 and 4

Answer 2

Answer:

x²-7x+12=0

→x²-4x-3x+12=0

→x(x-4) -3(x-4) =0

→(x-3) (x-4) =0

→Therefore, x=3 or x=4

But the roots are greater than 0 I.. e.

Delta>0

Therefore, the number of real roots is 0(zero).
