| ① | Multiply each term of $ \left( \color{blue}{2x+10}\right) $ by each term in $ \left( -2x+3\right) $. $$ \left( \color{blue}{2x+10}\right) \cdot \left( -2x+3\right) = -4x^2+6x-20x+30 $$ |
| ② | Combine like terms: $$ -4x^2+ \color{blue}{6x} \color{blue}{-20x} +30 = -4x^2 \color{blue}{-14x} +30 $$ |
