Hi all! Would anyone be able to explain the reasoning behind this as attached? I get how to solve the top line of the equation with the quadratic formula. But how does it equate to 0 because (x-2)^2 can't simply disappear, there must be an explanation to get rid of it. A hint is provided but I have no clue what 'multiply both sides by a polynomial to clear fractions' means. Any help would be appreciated as most people in my class are struggling on how to prove to solve this also. Please try and explain as simply as possible :)

hmm (x-2)(x-2) is x^2+4-4x. so that means you'd have to cancel it out by... is this a fraction? if so then i think the hint might've wanted you to multiply what was in the denominator to both sides of the equation which then makes the denominator dissapear (by canceling it out) and ultimately 'clears the fractions'.

Step-by-step explanation:

i cannot see the picture because my school computer blocks images so i cannot fully understand the question so i tried based on your words... sorry if its inaccurate or made no sense :c

when is this due? i get my phone back tomorrow and i would like to try this problem tomorrow when i can see the picture you provided on it.

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

i did it myself and i got 4.2 (b) hope its right
