((-2.18*10^6)x^2)-.852x+.045 solve for x.

((-2.18*10^6)x^2)-.852x+.045 = 0 solve for x

using quadratic root formula to solve for x :

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

= ( -0.852 + / sqrt( 0.852^2 + 4*0.045*2.18*10^6)) /-2*2.18810^6

=( 0.852 + /- 626.42)/-2*2.18*10^6

x = -143*10^-6

x = +143.48*10^-6
