z=\frac{3\times 4}{1-2}+\frac{6\times 2^{2}}{1\times 2-4\times 2}
Calculate 2 to the power of 2 and get 4.
z=\frac{12}{1-2}+\frac{6\times 2^{2}}{1\times 2-4\times 2}
Multiply 3 and 4 to get 12.
z=\frac{12}{-1}+\frac{6\times 2^{2}}{1\times 2-4\times 2}
Subtract 2 from 1 to get -1.
z=-12+\frac{6\times 2^{2}}{1\times 2-4\times 2}
Fraction \frac{12}{-1} can be rewritten as -12 by extracting the negative sign.
z=-12+\frac{6\times 4}{1\times 2-4\times 2}
