(X+1)(X+1)46=0
We multiply parentheses ..
(+X^2+X+X+1)46=0
We multiply parentheses
46X^2+46X+46X+46=0
We add all the numbers together, and all the variables
46X^2+92X+46=0
a = 46; b = 92; c = +46;
Δ = b2-4ac
Δ = 922-4·46·46
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
Stosujemy wzór:$X=\frac{-b}{2a}=\frac{-92}{92}=-1$
