What 2 numbesr multiply go get -6 and add to get 1
-2 and 3
(x-2)(x+3)=0
set each to zero
x-2=0
x=2
x+3=0
x=-3
{2,-3}
The answer is C: difference of cubes
proof
x^6-27=(x^2)^3 - 3^3, because (x^2)^3 =x^2*3=x^6

Given:
m∠APB = 19°
To find:
The arc measure of DBC.
Solution:
∠APB and ∠DPC are vertical angles.
By vertical angle theorem:
m∠APB = m∠DPC
m∠DPC = 19°
DB is the diameter of the circle.
Angle measure of diameter = 180°
m∠DPB = 180°
m∠DPC + m∠CPB = m∠DPB
19° + m∠CPB = 180°
Subtract 19° from both sides.
19° + m∠CPB - 19° = 180° - 19°
m∠CPB = 161°
<em>The measure of central angle is equal to the measure of intercepted arc.</em>
m∠CPB = m(ar CPB)
m(ar CPB) = 161°
The arc measure of DBC is 161°.
