Why are quadratic equations set equal to zero?
Because zero is
an easy number
to work with
Because setting it
equal to zero
helps us find the
y-intercepts.
Because we are
trying to find the
x-intercepts and
that happens
when y=0.
None of the
above

Answer: Because we are trying to find the x-intercepts and the y-intercepts That would be (C)

Step-by-step explanation:

Self explanatory question, you set a quadratic equation to zero

For example: x 2 – 6 x = 16 equals to x 2 – 6 x – 16 = 0

Then, you would factor, that equals to (x – 8)( x + 2) = 0

(X-8)=0 (X+2)=0

X+2=0

-2 =-2

X=-2

X-8=0

+8 =+8

X=-8

To check you would simply plug in the values into the quadratic equation. They would both equal 16=16

:) Multiple choices are difficult but the best answers are C or D GO WITH YOUR GUT!
