show that X square + 4 x + 6 has no zero
Answers
Well, to say,
x²+4x+6
has zeroes but they aren't REAL...
please try to understand my point and DON'T take it offensively...
We have a method called as the sridharacharya or the Indian method for determining the roots of a quadratic equation.
The equation is like that of the picture above.
By putting the values we have 2 roots....which are COMPLEX or IMAGINARY and not REAL...
So in my point of view, you should specify IMAGINARY or REAL in your question...
Otherwise , why not , every quadratic equation has roots...
But as you are lower class, IMAGINARY numbers have not been taught, so at your level I agree with your statement...
HOPE THIS HELPS...

Answer:
on calculating the discriminate we found that it is less that zero. so the equation has no real roots.
