First step, list your A,B,C’s.
A=5
B=-9
C=-116

The quadratic formula is:
y= -b +/- the square root of b^2-4(a)(c)
———————————————————-
2a

^ all of that is divided by 2(a)

now you wanna fill in your a,b,c’s.

(im gonna use sr to shorten (s)quare (r)oot)

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.
