x = 1/2 (7-sqrt(4449))

x = 1/2 (7+sqrt(4449))

Just use the quadratic formula ^_^

using the quadratic formula

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

a=1

b=7

c=0

(-(-7) +/- sqrt (-7^2-4*1*0)) / 2*1

(7 +/- sqrt (49-0)) / 2

(7 +/- 7) / 2

(7+7) / 2 = 7

(7-7) / 2= 0

x= 7, 0

or you can factor

x^2-7x=0

x (x-7)=0

separate the equation to get

x=0 and x-7=0

x=0 and x=7

so x= 7, 0
