What is the zeros of y=x(x+5)(x-8)

sertanlavr [38]

y=x(x+5)(x-8)

The zeros of y=x(x+5)(x-8), means to solve the value of x, when y =0

y=x(x+5)(x-8) = 0

x(x+5)(x-8) = 0

x = 0 or (x+5) = 0 or (x - 8) = 0

x = 0 x + 5 = 0 x - 8 = 0
 x = 0 -5 x = 0 + 8
 x = -5 x = 8

Hence the zeros are x = 0, x = -5, x = 8
