Let's simplify this expression:
5x(3x-2) = 15x^2 - 10x2(x-3) = 2x - 6-3x(4x+4) = -12x^2 - 12x
Combining these terms:
15x^2 - 10x + 2x - 6 - 12x^2 - 12x = 3x^2 - 20x - 6
The simplified expression is:
3x^2 - 20x - 6
Therefore, the given expression is not equal to 3x^2 + 14.
Let's simplify this expression:
5x(3x-2) = 15x^2 - 10x
2(x-3) = 2x - 6
-3x(4x+4) = -12x^2 - 12x
Combining these terms:
15x^2 - 10x + 2x - 6 - 12x^2 - 12x = 3x^2 - 20x - 6
The simplified expression is:
3x^2 - 20x - 6
Therefore, the given expression is not equal to 3x^2 + 14.
