Can the quadratic formula be used to solve a linear equation?
The degree of an equation is the highest power of the variable in which the equation is given. A linear equation is of degree 1 , whereas the degree of a quadratic equation is 2. The number of solutions of an equation is equal to the degree of the equation. Also, the number of terms is equal to (degree+1).
Let us consider a quadratic equation a
According to the quadratic formula,
Now if you wish to use this formula to solve a linear equation, you will not get the term a
Also the quadratic formula gives two values of the variable but a linear equation can have only one solution.
Hence you cannot use the quadratic formula to solve a linear equation.
