Question
4p^2+8p+1=0
Answers
Reiny
Are we solving??
then ...
(2p + 1 )^2 = 0
2p + 1 = 0
2p = -1
p = -1/2
then ...
(2p + 1 )^2 = 0
2p + 1 = 0
2p = -1
p = -1/2
Reiny
had a mental lapse
4p^2 + 8p + 1 = 0
p = (-8 ± √48)/8
= (-8 ± 4√3)/8
= (-2 ± √3)/2
4p^2 + 8p + 1 = 0
p = (-8 ± √48)/8
= (-8 ± 4√3)/8
= (-2 ± √3)/2
