when you get to x^2 -x -2 = 0 - skip the next couple of steps. that equation factors to (x-2)(x+1) =0 - and then get the values of x

Можно сразу избавиться от множителя, превратив числитель в 4.

My brain: start with 2: works: done

Wonderful i like very much mathematicas

x^2-x-2=0 =>(x-2)(x+1)=0 =>x={2,-1)ans

-1, 2.

x=2or-1

Wouldn't you use the logarithm right away

x^- x-2=0 па то се види са Марса да је (x+1)×( x-2)=0 Компликујеш
