SOLUTION: Solve by using the quadratic formula: {{{ 4x^2+1=8x }}} Here's my work: a= 4 b= -8 c= 1 -(-8) +/- sqrt((-8)^2-4(4)(1)/8 8 +/- sqrt(48)/8 I don't know what to

Question 1073899: Solve by using the quadratic formula:

Here's my work:

Solve by using the quadratic formula:

 = 

Here's my work:
a= 4                                           correct
b= -8                                          correct
c= 1                                           correct

 -(-8) +/- sqrt((-8)^2-4(4)(1)/8               You missed one parenthesis  -(-8) +/- sqrt((-8)^2-4(4)(1))/8

 8 +/- sqrt(48)/8                              correct

I don't know what to do after that             =  =  = .  It is your final answer.

Thanks!!!                                      Please.
