Показать ответ. (2). (b) Solve the equation 52x – 12(5x) + 35 = 0. (4).

Simple and best practice solution for cos*2x+3sinx+1=0 equation. Check how easy it is, and learn it for the future. Our solution is simple, and easy to understand, so don`t hesitate to use it as a solution of your homework.

So it was factored incorrectly. 2cos^2x=3sinx 2(1-sin^2x)=3sinx 2-2sin^2x=3sinx 2sin^2x+3sinx-2=0 (2sinx-1)(sinx+2)=0 sinx=1/2 or sinx=-2 Sinx cannot equal -2 so, sinx=1/2 x=[30 +-n(360)]degrees and x=[(150)+-n(360)degrees] These are all the solutions.
