m^{2}-4m+4-2^{3}=\left(m+1\right)m-5+\sqrt{10\sqrt{9}-3\left(-2\right)}
Use binomial theorem \left(a-b\right)^{2}=a^{2}-2ab+b^{2} to expand \left(m-2\right)^{2}.
m^{2}-4m+4-8=\left(m+1\right)m-5+\sqrt{10\sqrt{9}-3\left(-2\right)}
Calculate 2 to the power of 3 and get 8.
m^{2}-4m-4=\left(m+1\right)m-5+\sqrt{10\sqrt{9}-3\left(-2\right)}
Subtract 8 from 4 to get -4.
m^{2}-4m-4=m^{2}+m-5+\sqrt{10\sqrt{9}-3\left(-2\right)}
Use the distributive property to multiply m+1 by m.
m^{2}-4m-4=m^{2}+m-5+\sqrt{10\times 3-3\left(-2\right)}
Calculate the square root of 9 and get 3.
m^{2}-4m-4=m^{2}+m-5+\sqrt{30-3\left(-2\right)}
Multiply 10 and 3 to get 30.
m^{2}-4m-4=m^{2}+m-5+\sqrt{30+6}
Multiply -3 and -2 to get 6.
m^{2}-4m-4=m^{2}+m-5+\sqrt{36}
Add 30 and 6 to get 36.
m^{2}-4m-4=m^{2}+m-5+6
Calculate the square root of 36 and get 6.
m^{2}-4m-4=m^{2}+m+1
Add -5 and 6 to get 1.
m^{2}-4m-4-m^{2}=m+1
Subtract m^{2} from both sides.
-4m-4=m+1
Combine m^{2} and -m^{2} to get 0.
-4m-4-m=1
Subtract m from both sides.
-5m-4=1
Combine -4m and -m to get -5m.
-5m=1+4
Add 4 to both sides.
-5m=5
Add 1 and 4 to get 5.
m=\frac{5}{-5}
Divide both sides by -5.
m=-1
Divide 5 by -5 to get -1.
