# What is 11^2 - 6 * 11 + 5 * 11?

Apr 3, 2016

11^2−6⋅11+5⋅11 = 110

#### Explanation:

${11}^{2} = 121$

6⋅11 = 66

5⋅11 = 55

121 − 66 = 55

$55 + 55 = 110$

We can immediately pull out a factor of $11$:

${11}^{2} - 6 \cdot 11 + 5 \cdot 11 = 11 \left(11 - 6 + 5\right)$

Since $11 - 6 + 5 = 10$:

$= 11 \left(10\right) = 110$
