Answer:
(1): "x7" was replaced by "x^7". 1 more similar replacement(s).
Equation at the end of step 1
(0 - (3 • (x5))) • (2•3x7)
Equation at the end
(0 - 3x5) • (2•3x7)
Multiplying exponential expressions
3.1 x5 multiplied by x7 = x(5 + 7) = x12
Multiplying exponents:
3.2 31 multiplied by 31 = 3(1 + 1) = 32
Final result :
( -32•2x12)

42 is the answer to your question
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
