Arrange the steps in the correct order to solve this trigonometric equation. 2sin^2x - sin x = 0 for 0 degrees less than equal to x less than equal to 90

1.  2sin^2x-sinx-1=0

2. substituting sinx with u  

3. 2u^2-u-1  

4. (2u+1)(u-1)=0

5. u=1 and u=-1/2

6. replacing u with sinx so sinx=1 sinx=-1/2  

7. x=90 0  <x<90

8.x=90

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
