4c^2-(9(4c-9))=0
We calculate terms in parentheses: -(9(4c-9)), so:We get rid of parentheses
9(4c-9)
We multiply parentheses
36c-81
Back to the equation:
-(36c-81)
4c^2-36c+81=0
a = 4; b = -36; c = +81;
Δ = b2-4ac
Δ = -362-4·4·81
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
Stosujemy wzór:$c=\frac{-b}{2a}=\frac{36}{8}=4+1/2$
