Question

2x^2+9x+6=0 quadtratic equation

Answer 1

Hello from MrBillDoesMath!

Answer:

x = ( -9 + sqrt(33) ) /4

and

x = ( -9 - sqrt(33) ) /4

Discussion:

Using the quadratic formula with a = 2, b = 9 and c = 6 gives

x = ( -b +\- sqrt(b^2-4ac) )/2a

x = ( -9 +\- sqrt(9^2 - 4*2*6)) / (2*2)   =>

x = ( -9 +\- sqrt (81- 48)) / 4                 =>

x = ( -9 +\- sqrt(33) ) /4

Thank you,

MrB
