Solution
The correct option is A True The given quadratic equation is ax2+bx+c
Let us write this quadratic equation into a product of two linear factors i.e.
ax2+bx+c=(x+d)(x+e)
Then the roots of this quadratic equation are −d and −e which we get using x+d=0 and x+e=0.
So, we get the roots by equating each factors to zero.
