Answer:

Factor of
m^(2)-12m+20 is
=\left(m-2\right)\left(m-10\right)

Explanation:

We need to find the factors of
m^(2)-12m+20


\mathrm{Break\:the\:expression\:into\:groups}


=\left(m^2-2m\right)+\left(-10m+20\right)


\mathrm{Factor\:out\:}m\mathrm{\:from\:}m^2-2m\mathrm{:\quad }m\left(m-2\right)\\


\mathrm{Factor\:out\:}-10\mathrm{\:from\:}-10x+20\mathrm{:\quad }-10\left(m-2\right)


=m\left(m-2\right)-10\left(m-2\right)


=\left(m-2\right)\left(m-10\right)

Hence, factor of
m^(2)-12m+20 is
=\left(m-2\right)\left(m-10\right)
