However, that result is not tight. The computation can be performed exactly via
single-use expressions implemented in this library:

```jldoctest quickstart
julia> quadratic_expansion(A, 1.0, 0.5)
2×2 IntervalMatrix{Float64, Interval{Float64}, Matrix{Interval{Float64}}}:
[1.0, 4.50001] [-2.0, 1.0]

[1.0, 4.5] [-2.0, 1.0]
[-3.0, 1.5] [1.0, 7.0]
```
We now obtain an interval matrix that is strictly included in the one obtained from
the naive multiplication.
