F(x) = 2x² + 7x - 5
g(x) = -8x² - 3x + 5
g(x) + f(x) = -8x² - 3x + 5 + 2x² + 7x - 5 = - 6x² + 4x
Answer: -6x² + 4x

Answer:
Option (3)
Step-by-step explanation:
w =
Since, cos(225) = cos(180 + 45)
= -cos(45) [Since, cos(180 + θ) = -cosθ]
= -
sin(225) = sin(180 + 45)
= -sin(45)
= -
Therefore, w =
=
=
z = 1[cos(60) + i(sin(60)]
=
=
Now (w + z) =
=
=
=
Therefore, Option (3) will be the correct option.
