Balanced:2 K + Br2 ----> 2 KBr
neg(-k) + neg(-k) = k + k = 2k = 4
j=-3 and k=2
5k + 2 = -2 Therefore, 5k = -4 k = -4/5 k = -0.8
k = 2 7 + (5 x 2) = 17 (8 x 2) + 1 = 17
They are +/- 5*sqrt(2)
Equation: x^2 +2kx +10x +k^2 +5 = 0 Using the discriminant: (2k +10)^2 -4*1*(k^2 +5) = 0 Solving the discriminant: k = -2
Yes, they are exactly the same, both of them increment k in 1.
Using the discriminant of b^2 -4ac = 0 the value of k works out as -2
y = 3x + 2x^2 + k where k is any number
The salt potassium bromide. The chemical equation is 2 K + Br2 -> 2 KBr.
