# How do you expand and simplify 4(m-2)(3m-1)?

Dec 10, 2016

$12 {m}^{2} - 28 m + 8$

#### Explanation:

First, cross multiply the terms within parenthesis by cross multiplying:

$4 \left(3 {m}^{2} - m - 6 m + 2\right)$

Next we can combine like terms with the parenthesis:

$4 \left(3 {m}^{2} - 7 m + 2\right)$

Now we can distribute the $4$ over the terms within the parenthesis:

$12 {m}^{2} - 28 m + 8$
