Best Answer

You use the identity sin2x + cos2x = 1 (to simplify the expression in parentheses), and convert all functions to sines and cosines.

sec x tan x (1 - sin2x)

= (1/cos x) (sin x / cos x) (cos2x)

= (sin x / cos2x) cos2x

= sin x

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is X squared plus 6x minus 55?

Without knowing what "x" is, we cannot say what the answer will be. And without knowing the answer, we cannot solve for "x". Set x at zero, for example. Zero squared is zero, plus 6 time zero which is zero, minus 55. Your answer is then -55. Set x at one, for example. One squared is one, plus 6 times 1 which is six, minus 55. Your answer is then -48. Etc.
