Question

9.What are the zeros/roots of the quadratic shown?

Answer 1

Answer:

9. b

10. d

Step-by-step explanation:

For number 9, the zeros are the x-intercepts (the ones on the x-axis). Number 10 is +/-3 because if you factor out $x^{2} -9$, it'll give you $(x+3)(x-3)$.

Shown work:

$x+3=0$      $x-3=0$

   $-3$  $-3$          $+3$  $+3$

-------------     --------------

  $x=-3$            $x=3$
