Find the zeroes o

Answer :

To find the zeros of the polynomial let us first solve the polynomial by equating it to zero. Factorizing the given polynomial

4x2 + 8x = 0


4x(x + 8) = 0


4x = 0 or x + 8 = 0


Now solving the first part,


4x = 0


x = 0/4


x = 0


Now solving the second part,


x + 8 = 0


x = -8


When we compare the above quadratic equation with the generalized one we get,


ax2 + bx + c = 0


a = 4, b = 8, c = 0


Sum of zeroes = -b / a


= -8 / 4


= -2


Product of zeroes = c / a


= 0 / 4


= 0
