Write a quadratic function with zeroes 0 and 8.
Jlenok [28]

Answer:

x^2-8x=0

Step-by-step explanation:

the quadratic function should be as follows:

x^2-8x=0

Now let's confirm that the zeros of the function are 0 and 8

x^2-8x=0=x(x-8)=0

Therefore we can see that if x = 0

0^2*8*0=0\\0=0

the equation is fulfilled

And we also have (x-8)

for this expresion to be equal to zero:

x-8=0\\x=8

thus, if x = 8

8^2-8*8=0\\64-64=0\\0=0

the equation is also fulfilled

The zeros of the quadratic function x^2-8x=0 are 0 and 8.
