Answer:

<u>The answer is the option B</u>

4m-24n+3

Step-by-step explanation:

we have

17m-12n-1+4-13m-12n

Group terms that contain the same variable

(17m-13m)+(-12n-12n)+(-1+4)

Combine like terms

(4m)+(-24n)+(3)

4m-24n+3

What number must you add to the polynomial below to complete the square? x2 - 3x
USPshnik [31]
The coefficient of the x-term is -3. Add the square of half of that.
.. (-3/2)² = 9/4 . . . . . . the number you need to add.

x² -3x +9/4 = (x -3/2)²

_____
If the x² term has a coefficient other than 1, you need to factor that out first and deal with the remaining binomial. For example,
.. 2x² -6x = 2(x² -3x)
For this you would need to add 9/4 inside parentheses to get
.. 2(x² -3x +9/4) = 2(x -3/2)²
Of course, to keep the original value, you would need to subtract 2*(9/4) outside parentheses.
.. 2x² -6x = 2(x -3/2)² -9/2
