What standard form polynomial expression represents the area of the triangle? 3g^2-6g+2

Area of Rectangle = length times width

lets say length = 2x-4

width = x+5

Note: you can switch these around, width could be 2x-4 and length could be x+5, it doesnt matter.

With that being said:

length * width = area

(2x-4)(x+5)=area

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
