186=(4x^2+8x)/2.
We move all terms to the left:
186-((4x^2+8x)/2.)=0
We multiply all the terms by the denominator
-((4x^2+8x)+186*2.)=0
We calculate terms in parentheses: -((4x^2+8x)+186*2.), so:We get rid of parentheses
(4x^2+8x)+186*2.
We add all the numbers together, and all the variables
(4x^2+8x)+372
We get rid of parentheses
4x^2+8x+372
Back to the equation:
-(4x^2+8x+372)
-4x^2-8x-372=0
a = -4; b = -8; c = -372;
Δ = b2-4ac
Δ = -82-4·(-4)·(-372)
Δ = -5888
Delta is less than zero, so there is no solution for the equation
