Polynomials

Solve the following in box method:

3 to the second power times 16x minus 18=-6

To solve this using the box method, we will first create a box with two rows and two columns:

-------------------------------
| | |
-------------------------------
| | |
-------------------------------

Next, we will label the top row with the terms of the polynomial:

-------------------------------
| 3x | -18 |
-------------------------------
| | |
-------------------------------

Then, we will multiply the terms in the top row together and fill in the box:

-------------------------------
| 48x - 54 |
-------------------------------
| |
-------------------------------

The equation now becomes:

3x(16x) - 18 = -6

48x^2 - 54 = -6

Next, we will isolate the variable by adding 54 to both sides:

48x^2 = 48

Divide by 48 on both sides:

x^2 = 1

Finally, take the square root of both sides to solve for x:

x = ±1

Therefore, the solutions are x = 1 and x = -1.
