1 answer:
Answer:
A. x - 4
D. x + 8
Step-by-step explanation:
<em><u>To find the two binomial that are factors of the trinomial, you split the middle term into two:</u></em>
<em><u /></em> + 4x - 32
- 4x + 8x - 32
<em><u>Group:</u></em>
( - 4x) (8x - 32)
<em><u>Take out GCF (Greatest Common Factor):</u></em>
x(x - 4) 8(x - 4)
(x + 8) (x - 4)

The equation of the axis of symmetry is x=1.5.
_____
If you want to find it analytically, you can put the equation in standard form.
y = -3(x -2)² +4 -(3x -6)
y = -3x^2 +9x -2
This is of the form y = ax² +bx +c with a=-3 and b=9. The axis of symmetry is given by ...
