BRO USED the quadratic formula is a closed-form expression describing the solutions of a quadratic equation. Other ways of solving quadratic equations, such as completing the square, yield the same solutions.
Given a general quadratic equation of the form
๐๐ฅ2 + ๐๐ฅ + ๐ = 0
๐๐ฅ2 + ๐๐ฅ + ๐ = 0๐๐ฅ2 + ๐๐ฅ + ๐ = 0V๐๐ฅ2 + ๐๐ฅ + ๐ = 0๐๐ฅ2 + ๐๐ฅ + ๐ = 0๐๐ฅ2 + ๐๐ฅ + ๐ = 0๐๐ฅ
