Hey im not sure why i get the wrong answer =/ appreciate any advice.
I get x = 2, -5
but the book says x = 2, 1/2
i got everything else right in this section of book but cant figure this one out. The book does say y= not x= which makes me wonder if its a mistake.
baah sorry guys i know i cant keep posting same thing clogs up thread.
but really hit a wall here.
i got the hang of easy ones but the book throws in different ones without explaining ><
i know i have to some how extract the 9 so that it is same term as the other one.
but cant work out how.
following what phrontister said in post #4
i would square the 2 to make it a 4 then times that by 9 and get 36 is that the first step?
im probably just clicking buttons here but
if above true its written
if thats right it makes sense or is it just gorilla math
phew lol my brain was going to explode like trying to squeeze a triangle into a circle hole.
thanks for the link but any chance you can take a glance at this method
it seems simple and i got the hang of it pretty quickly
i will go through the link you sent now thank you very much
EDIT : both seem really similar ^^
im so lost. I have been staring at this page for over an hour.
im stuck on step 3
i need to find the square root of 23749.98
#step 1 first we write it in pairs starting left from decimal point and to the right of decimal point easy
#step 2 then find a perfect square of 2 and book says only 1 is smaller so i place the 1 above and below radical (not sure if right word)
STEP #3 next i thought we had to see how many times 2 would go into the first two digits of the new radicand 1 37 ?? so 2 goes into 13 = 6 times why is this book saying 5 times arghh i dont get it >< plz aware me
