2(10x^2) + 22x -12

2(10x^2) + 2(11x) - 12

2(10x^2) + 2(11x) + 2 (-6)

2(10x^2 + 11x) + 2 (-6)

2 (10x^2 + 11x - 6)

2 (10x^2 - 4x + 15x - 6)

2 (2x (5x - 2) + 3 (5x - 2))

2 ((5x - 2) (2x + 3))

Finally, your answer is 2 (5x - 2) (2x + 3)

I=\textit{interest earned}\to &\$1575\\
P=\textit{original amount deposited}\to& \$6000\\
r=rate\to r\%\to \frac{r}{100}\\
t=years\to &7
\end{cases}
\\\\\\
1575=(6000)(r)(7)\implies \cfrac{1575}{(6000)(7)}=r\implies 0.0375=r
\\\\\\
r\%=0.0375\cdot 100\implies r=\stackrel{\%}{3.75}$

"color the piece according to your color chart." Do you have that? If you don't, I wouldn't worry, you still did all the work and got all the answers, so your teacher should be fine with it.
