Step: 1

Expanding the first bracket, we get:

2x(x) + 2x(4) - 3(x) - 3(4)

Simplifying further:

\$ 2x^2 + 8x - 3x - 12\$

Now, expanding the second bracket:

5(x+2) = 5x + 5(2)

Simplifying:

=5x + 10

Now, let’s combine the like terms in the expression:

\$ 2x^2 + 8x - 3x - 12 + 5x + 10 \$

Adding the like terms:

\$ 2x^2 + 10x - 2 \$

Explanation:

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