2300=100(10x^2+28.27)
We move all terms to the left:
2300-(100(10x^2+28.27))=0
We calculate terms in parentheses: -(100(10x^2+28.27)), so:We get rid of parentheses
100(10x^2+28.27)
We multiply parentheses
1000x^2+2827
Back to the equation:
-(1000x^2+2827)
-1000x^2-2827+2300=0
We add all the numbers together, and all the variables
-1000x^2-527=0
a = -1000; b = 0; c = -527;
Δ = b2-4ac
Δ = 02-4·(-1000)·(-527)
Δ = -2108000
Delta is less than zero, so there is no solution for the equation
