Answer:
3x3+12x
Step-by-step explanation:
According to the question,3x(x2+4)
In this question we have multiplication, addition and bracket...
To solve we will have to solve it stepwisely, following the BODMAS rule
Which means that bracket comes first followed by addition
3x(x2+4)
3x3+12x
This is the final answer... this question cannot be solved further because of their different variables,I mean one has x^3 and the other one is x...if you should compare the two,they are not the same...
Therefore the final answer is 3x3+12x
