Jackson used the process of completing the square to solve the equation 2x2−12x=−6.

Step-by-step explanation:

we are given equation as

Since, we have to solve it by using complete square

so, firstly we will complete square

and then we can solve for x

step-1:

Factor 2 from both sides

step-2:

Simplify it

step-3:

Add both sides 3^2

now, we can complete square

step-4:

Take sqrt both sides

step-5:

Add both sides by 3

we get

-50/3 is the final answer! : )

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
