Answer:

D

Step-by-step explanation:

To evaluate p(- 7) substitute x = - 7 into p(x) , that is

p(- 7)

= - 4((- 7)² + 8) - 9

= - 4(49 + 8) - 9

= - 4(57) - 9

= - 228 - 9

Factor the trigonometric equation.<br> cos2x-cosx
prisoha [69]

Cos(2x) = cos^2(x) - sin^2(x) - cos(x)

but sin^2(x) = 1 - cos^2(x)

cos(2x) - cos(x) = cos^2(x) - (1 - cos^2(x) ) - cos(x)

cos(2x) - cos(x) = cos^2(x) - 1 + cos^2(x) - cos(x)

cos(2x) - cos(x) = 2cos^2(x) - 1 - cos(x)

cos(2x) - cos(x) = (2cos(x) + 1)(cos(x) - 1)

I think this is what you have asked for.
