The quadratic equation whose only zero is 3 will be x²-6x+9.
What is a quadratic equation?
The polynomial having a degree of two or the maximum power of the variable in a polynomial will be 2 is defined as the quadratic equation and it will cut two intercepts on the graph at x-axis.
Given that the zeros of the quadratic equation is 3. So the equation will be:-
= (x-3) (x-3)
= x²-6x+9.
Therefore the quadratic equation whose only zero is 3 will be x²-6x+9.
