Step-by-step explanation: Please see the attachments below
Answer:
(a) x = -0.418 , -3.581
(B) c = 6.855, -1.855
Step-by-step explanation:
(A) We have given equation 

On comparing with standard quadratic equation 
a = 2, b = 8 and c = 3
So roots of the equation will be 
(b) 

a = 1, b = -5 and c= -14
So
25% is equal to 1/4 or .25 of a whole.
If you do 10 divided by .25 you get 40.
10 is 25% of 40.
0.75 is the decimal format.
For this case we have to define trigonometric relations of rectangular triangles that:
- The cosine of an angle is given by the leg adjacent to the angle on the hypotenuse of the triangle.
- The sine of an angle is given by the leg opposite the angle on the hypotenuse of the triangle.
Then, according to the figure we have:
