 Hello friends, welcome to the session. I am Alka and today we are going to find the roots of the quadratic equation given in question first above by applying the quadratic formula. Our equation is 2x square plus x plus 4 equal to 0. Now let's start with the solution. Our given equation is 2x square plus x plus 4 equal to 0. Now on comparing this equation with a x square plus bx plus c equal to 0 we get a equal to 2 b equal to 1 and c equal to 4. Therefore d equal to b square minus 4ac. This implies d equal to 1 square minus 4 into 2 into 4. This gives d equal to 1 minus 32. This implies d equal to minus 31. Here we see that d is less than 0. So the given equation has no real roots. Hope you understood the solution and enjoyed the session. Goodbye and take care.
