The square of a binomial expands as follows:
Expanding all the binomials, we have
Sum like terms:
Simplify terms appearing on both sides:
Move all terms involving k to the left and all numbers to the right:
Divide both sides by -20:
My only guess is a^2 + b^2 = c^2
Answer:
Step-by-step explanation:
identify the known ratio and the unknown ratio.
Set up the proportion.

Check the answer by plugging the result into the unknown ratio.
^^^^^^^^^^^^^^^^^^^^^^^^^^^
is the steps to solve your answer
To do this let's put 129 where X is, like this: -12(129)+14(129)-6(129)
Now we multiply -12 by 129, which is equal to -1548.
Now we multiply 14 by 129, which is equal to 1806.
Now we multiply -6 by 129, which is equal to -774.
Now, let's put these numbers into an equation, like this: -1548+1806-(-774).
The answer to this equation is 1032.
I hope this helps.
