Simplify the algebraic expression: x(x + 3) + x(2x - 4) + 6
marusya05 [52]

Step-by-step explanation:

x(x + 3) + x(2x - 4) + 6

First, let's distribute the x variable to each term in the first parenthesis:

x^{2} + 3x + x(2x - 4) + 6

Next, let's distribute the x variable to each term in the second parenthesis:

x^{2} + 3x + 2x^{2} - 4x + 6

Next, let's group like terms together:

(x^{2} + 2x^{2}) + (3x - 4x) + (6)

Finally, let's add or subtract like terms to get the result:

3x^{2} - x + 6
