Use the distributive property.
The multiplied form is
Explanation:
The distributive property tells us that:
#color(red)a*(b+c)#
#color(red)a*b+color(red)a*c#
So we can use this property to distribute the
#color(red)(-3n^2)(-2n^2+3n+4)#
#=color(red)(-3n^2) * (-2n^2) + color(red)(-3n^2) * (3n) + color(red)(-3n^2) * 4#
Now just multiply each group of terms together. Remember that two negatives make a positive.
#= 6n^4 - 9n^3 - 12n^2#
