The area of a rectangular piece of fencing is represented by the equation w(4w+4)=3, where w is the width of fencing in yards. Find the width of the fencing.

first solve out parenthesis and bring the 3 to the other side which will give you 4w^2+4w-3=0 factoring the polynomial will give you (w-2) and (w+4) set them both to zero and solve it and then plug each answer back into the original polynomial to see if they equal zero if they do that is your answer but if one of them doesnt then that wont be your answer

oh yea i didn't factor out correctly so yea im too lazy to figure out the correct factor so you can do that yourself

• math -

yeah. It's (2w+3)(2w-1), so w=1/2 or -3/2

lol thanks steve when i was doing it i completelyforgot about the 4 in front of the 4w^2
