Question

A parabola intersects the x-axis at x=3, equals, 3 and x=9.

Answer 1

Answer: x is 6

Step-by-step explanation:

where a and b are x intercepts given to us.

So rewriting in factored form:

y = ($x-3$)($x-9$)

so now you have to simplify it using the formula $y=$ $ax^{2}$$+$ $bx-c$

y= $x^{2}$- $12x$+$27$

so with this formula $x=\frac{-b}{2a}$ we can find the x coordinate

$x=\frac{-(-12)}{2(1)}$

and the answer would be 6
