May 4, 2016

$4 {x}^{2} + 11 x - 12$

Explanation:

$\textcolor{b l u e}{\text{Preamble about multiplication}}$

$2 \times 5$ gives the same answer as $5 \times 2$

so $2 \times 5 = 5 \times 2$

so $x 5 = x \times 5 = 5 \times x = 5 x$
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Write as $4 {x}^{2} + 5 x - 12 + 6 x$

Regrouping $\to 4 {x}^{2} + 5 x + 6 x - 12$

$4 {x}^{2} + 11 x - 12$
