Step-by-step explanation:
using the identity
cos2a = 2cos²a - 1 , then
cos2a
= 2[ 
(a + 
) ]² - 1
= 2 [ 
(a² + 
+ 2) ] - 1
= (a² + ) + 1 - 1
= (a² + ) ← thus verified
Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
x = −1 ± i√2
There's no real solutions
Step-by-step explanation:
1) 3 – 36i = 9a + 4bi
3 = 9a => a = 3/9 = ⅓
-36 = 4b => b = -36/4 = -9
2) a – 15i = -7 – (2b-3)i
a = -7
-15 = -(2b-3)
2b-3 = 15
2b = 18
b = 18/2= 9
