Answer:
Step-by-step explanation:
Add or subtract multiples of 360° to find coterminal angles.
<u>Positive</u>
75° +360° = 435°
75° +2×360° = 795°
<u>Negative</u>
75° -360° = -285°
75° -2×360° = -645°
Answer:
• x = -4, x = 0, x = 1
Step-by-step explanation:
x is a factor of all terms, so x=0 is a zero. (Eliminates choices 1 and 5.)
The sum of coefficients is 0, so x=1 is a zero. (Eliminates choices 3 and 4.)
Reversing the sign of the odd-degree terms gives signs of -++, so there is one sign change, hence one negative real root (by Descartes' rule of signs). This confirms choice 2 as the answer.
