Use the method of completing the square to transform the quadratic equation into the equation form (x + p)2 = q. -6x2 + -6x + 12 = 0 A) (x + 2.5)2 = 0.75 B) (x + 2.5)2 = -0.75 C) (x + 0.5)2 = 2.25 D) (x + 0.5)2 = -2.25

Option C

Step-by-step explanation:

we have

step 1

Group terms that contain the same variable, and move the constant to the opposite side of the equation

step 2

Factor -6 leading coefficient'

step 3

Complete the square

Remember to balance the equation by adding the same constants to each side

step 4

Rewrite as perfect squares

simplify

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
