Expanding the first term, we get: 2x(x) + 2x(4) - 3(x) - 3(4) Simplifying further: \$ 2x^2 + 8x - 3x - 12\$ Now, expanding the second term: 5(x + 2) = 5x + 5(2) Simplifying: 5x + 10 Now let’s add the results of the first and second expansions: \$2x^2 + 8x - 3x - 12 + 5x + 10\$ Adding the like terms: \$ 2x^2 + 10x - 2 \$ Thus, the simplified expression is \$ 2x^2 + 10x - 2 \$. |

We simplified the terms inside each bracket and then added similar terms together. This gave us the simple expression: \$ 2x^2 + 10x - 2 \$. |
