Question

How do you solve 2x^2-11x+5=0 using the quadratic formula ? Please include all steps

Answer 1

First you have to define a, b and c
a=2
b=-11
c=5

Answer 2

The formula is
x = (-b +-sqroot(b^2 - 4ac)) / 2a

x = (--11 +-sqroot([-11^2] - 4*2*5)) / 2*2

x = (11 +-sqroot(121 - 40)) / 4

x = (11 +- 9) / 4

x1= 20/4 = 5

x2 = 2/4 = 2

Answer 3
