16-4-\left(-k+2\right)=0
Calculate -4 to the power of 2 and get 16.
12-\left(-k+2\right)=0
Subtract 4 from 16 to get 12.
12-\left(-k\right)-2=0
To find the opposite of -k+2, find the opposite of each term.
10-\left(-k\right)=0
Subtract 2 from 12 to get 10.
-\left(-k\right)=-10
Subtract 10 from both sides. Anything subtracted from zero gives its negation.
-k=\frac{-10}{-1}
Divide both sides by -1.
-k=10
Fraction \frac{-10}{-1} can be simplified to 10 by removing the negative sign from both the numerator and the denominator.
k=-10
Multiply both sides by -1.
