Answer:
25x^2 -40x + 16
Step-by-step explanation:
(5x-4)^2
(5x-4)(5x-4)
FOIL
first 5x*5x =25x^2
outer 5x*-4 = -20x
inner 5x*-4 = -20x
last = -4*-4 = 16
Add them together
25x^2 -20x -20x+ 16
Combine like terms
25x^2 -40x + 16

Answer:
Therefore, 60 degrees and -300 degrees are coterminal angles. The -300 degree rotation is pictured here. Infinitely many other angles are coterminal to 60 degrees. Each time you add or subtract a multiple of 360 degrees to 60 degrees, you will end up with a coterminal angle of 60 degrees
