if something is in factored form it means (x+or-c)(x+or-c) so to expand we just use FOIL First Outside Inside Last
so if we have for example the expression (x-2)*(x+3)=0 we get in expanded form
x^2-2x+3x-6= x^2+x-6=0
Hope this helps! Need anything explained further please just ask! Please rate! Thank you so much!
