| ① | Multiply each term of $ \left( \color{blue}{-2x+3}\right) $ by each term in $ \left( 4x-5\right) $. $$ \left( \color{blue}{-2x+3}\right) \cdot \left( 4x-5\right) = -8x^2+10x+12x-15 $$ |
| ② | Combine like terms: $$ -8x^2+ \color{blue}{10x} + \color{blue}{12x} -15 = -8x^2+ \color{blue}{22x} -15 $$ |
