Factor the trigonometric expression sin2x 5 sin x 14 Selec

Factor the trigonometric expression.

sin²x + 5 sin x - 14

Select one:

a. (sin x - 7)(sin x + 2)

b. (sin x + 7)(sin x - 2)

c. (sin² x + 7)(sin x - 2)

d. (sin x - 14)(sin x + 1)

Solution

given sin^2 x + 5sinx -14

sin^2 x + 7sinx -2sinx -14

   sinx(sinx +7) -2 (sinx+7)

(sinx+7) (sinx-2)

SO OPTION B IS ANSWER

B --->ANSWER
