The answer is K=-1/5
You suppose to divide both sides by 3.
Move the constant to the left-hand side and change its sign Use a^2 + 2 ab+ b^2 = (a+b)^2 to factor the expression.
The only way an exponentiation can be 0 is when the base equals 0.
Move the constant to the right-hand side and change its sign.
Divide both sides of the equation by 5.
