| ① | Multiply each term of $ \left( \color{blue}{3x-2}\right) $ by each term in $ \left( 8x-7\right) $. $$ \left( \color{blue}{3x-2}\right) \cdot \left( 8x-7\right) = 24x^2-21x-16x+14 $$ |
| ② | Combine like terms: $$ 24x^2 \color{blue}{-21x} \color{blue}{-16x} +14 = 24x^2 \color{blue}{-37x} +14 $$ |
