Answer:
The equation is;
x^2 + 4x + 4 = 0
Explanation:
Here, we want to give a quadratic equation with a real solution that has a multiplicity of two
Generally, there are only two solutions to a quadratic equation since it is a polynomial of degree two
Since we have a multiplicity of 2, it means that the real roots are repeated
Let us have a solution of x = -2
With the multiplicity;
we have x + 2
So let us expand this
(x+2)(x+2)
= x^2 + 4x + 4
The equation is;
x^2 + 4x + 4 = 0
