What is the product of (4n-5)(4n-4)

Step-by-step explanation:

To figure this out imma show you a much easier way they is called a box method and i want you to creat a box and put on the top (4n-5) know on the other side where there is a red line on the paper put (4n-4) know this box method is simple all u have to do is multiply its simple and easy if you ever get stuck on something like this you can always use the box method.

16n^2 -36n+20

Step-by-step explanation:

You have to distribute,

so multiply 4n x 4n = 16n^2

then 4n x -4 = -16n

-5 x 4n = -20n combine with -16 = -36n

-5 x -4 = 20

simplifying

5(x + -6) = 2(x + 3)

reorder the terms:

5(-6 + x) = 2(x + 3)

(-6 * 5 + x * 5) = 2(x + 3)

(-30 + 5x) = 2(x + 3)

reorder the terms:

-30 + 5x = 2(3 + x)

-30 + 5x = (3 * 2 + x * 2)

-30 + 5x = (6 + 2x)

solving

-30 + 5x = 6 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-30 + 5x + -2x = 6 + 2x + -2x

combine like terms: 5x + -2x = 3x

-30 + 3x = 6 + 2x + -2x

combine like terms: 2x + -2x = 0

-30 + 3x = 6 + 0

-30 + 3x = 6

add '30' to each side of the equation.

-30 + 30 + 3x = 6 + 30

combine like terms: -30 + 30 = 0

0 + 3x = 6 + 30

3x = 6 + 30

combine like terms: 6 + 30 = 36

3x = 36

divide each side by '3'.

x = 12

simplifying

x = 12

this should .
