I'm having some trouble with this concept. Expression: 3x(4x + 5) and another one -2x(3x - 12)

Thanks. I have another question, what's 14x^2 + x^2? Is that 15x^2?
And 2x(x + 3) = 3x + 3? Or 2x^2 + 3?

Thank you. This one's got me stumped. 4x^2(5x + 6) + 2x(x^2 + 10x - 12)
I got 20x^3 + 24x^2 + 4x^3 + 20x^2 - 24x = 24x^3 + 44x^2 - 24x
