Follow the process of completing the square to solve 2x2 + 8x - 12 = 0. after adding b2 to both sides of the equation in step 4, what is the constant on the right side of the equation?

We have that
2x² + 8x - 12 = 0

Group terms that contain the same variable, and move the constant to the opposite side of the equation
(2x² + 8x)=12 

Factor the leading coefficient 

2*(x² + 4x)=12 > divide by 2> (x² + 4x)=6

Complete the square. Remember to balance the equation by adding the same constants to each side

(x² + 4x+4)=6+4

(x+2)²=10

the constant on the right side of the equation is 10

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
