50 POINTS, I NEED IT QUICK PLSS
olga nikolaevna [1]

The thing that's wrong with the equation is that 2 shouldn't be multiplied by 4 but should have been added.

<h3>How to illustrate the information?</h3>

From the information given, it can be seen that the equation is:

(3x²)(-2x⁴) = 3(-2)x² × x⁴ = 6x^8

Based on the information above, this calculation is incorrect. The correct calculation will be:

(3x²)(-2x⁴) = 3(-2)x² × x⁴

= -6x^6

Therefore, the multiplication should be an addition of the power.
