# How do you simplify (U-6)^2?

Dec 8, 2016

${U}^{2} - 12 U + 36$

#### Explanation:

To simplify and get into quadratic form you cross multiple the term in parenthesis by itself:

${\left(U - 6\right)}^{2} \to \left(U - 6\right) \left(U - 6\right) \to$

$\left(U \cdot U\right) - \left(6 \cdot U\right) - \left(6 \cdot U\right) + 36 \to$

${U}^{2} - 12 U + 36$
