Answer:4
Step-by-step explanation:
4
To find out the number of real solutions, we use something called "the discriminant". This is usually given the symbol "<span>Δ", pronounced "delta"
</span><span> Δ = b^2 - 4ac, where a is the x^2 coefficient, b is the x coefficient and c is the integer
</span>
When Δ = 0, there is one real solution, when Δ < 0, there are no real solutions, and when Δ > 0, there are 2 real solutions
So, substituting the values in, we get:
Δ = (20)^2 - 4(-4)(-25) = 0
Therefore, there is one real solution to the polynomial given.
