1. solve the following equation using the quadratic formula: 3x2 + 6x + 8 = 6.
2. is the quadratic formula the most efficient way to solve this equation? why or why not?

1.

2. Quadratic formula is the most efficient way to solve this equation.

Step-by-step explanation:

We have been given an equation . We are asked to solve our given equation using quadratic formula.

, where,

b = Coefficient of x term,

c = Constant,

a = Coefficient of term.

Upon substituting our given values, we will get:

Therefore, the solutions for our given equation are .

2. We cannot factor our given equation by splitting the middle term because there are no such numbers which add up-to 6 and whose product is 6.

Therefore, the quadratic formula is the most efficient way to solve this equation.

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
