This problem is bugging me...
sqrt(t-42)-sqrt(t+44)=83
I know the problem looks like this.
sqrt(t-42)=83+sqrt(t+44)
and then you square both sides
but im having a problem doing that :X
I know the formula is this (a-b)^2=a^2-2ab+b^2
and then i write it in ax^2 +bx +c = 0
If someone can just help me out with squareing both sides that would be great. im not sure my numbers are right as they are rather big.
Plz help, already tried google and looked through the book, just not the examples im looking for...
