4x^2 + 5x + 2     factor out the "4"

4(x^2 + (5/4)x + 2/4)

Take 1/2 of 5/4  =  (1/2)(5/4)  =   5/8 ....square this  = 25/64...add and subtract it within the parentheses

4( x^2 + (5/4)x + 25/64  + 2/4 - 25/64)        factor the first three terms, simplify the rest

4[ ( x+ (5/8))^2  +  32/64  25/64]

4 [ ( x + (5/8) )^2 +  7/64 ]    distribute the4 over the terms inside the parentheses

4(x + (5/8))^2  + 28/64

4 (x + (5/8))^2  +  7/16

Doesn't mattter ;P

No I didnt see it what did it say

Nobody care's ; )

Did you see the epilogue on the troll’s Peton Place post yesterday?

Combine like terms

4x^2+5x=9x^2

9x^2+2=0

solve as a normal problem as 9x+2=0

then 9x=2

divide

x=2/9

x=sqrt(2/9)
