Hi, having troubles once again, not a foggy what i'm doing wrong
question is
'by completing the square, solve the quadratic equation, giving your answer in surd form'
sorry i don't know how to put in that math notation stuff.
: xsquared + 3x - 5 = 0
this is where i got
(x + 3/2)squared - 29/4 = 0
x = -3/2 +or- squarerootof 29/4
whereas they get
x = -3/2 +or- squarerootof 29/2
other questions where i was expecting the last bit (the squareroot-of-bit) to be Something/4, the book was saying Something/2. i just dont see how they got there. please help
