Anderson could provide 0.5x2 + 4x + 8 = 0 has exactly one real root if the discriminant is 0,
<h3>What is quadratic equation?</h3>
Any equation that can be rewritten in standard form as where x represents an unknown, a, b, and c represent known numbers, and where a 0 is true is a quadratic equation. As there is no ax2 term when a = 0, the equation is linear rather than quadratic.
<h3>What is discriminant?</h3>
A polynomial's discriminant is a quantity that depends on the coefficients and enables for some root attributes to be inferred without actually computing them. It is actually a polynomial function of the original polynomial's coefficients.
<h3>According to the given information:</h3>
0.5x^2 + 4x + 8 = 0
The discriminant is computed utilizing:
d = b^2 - 4ac
Thus, we have:
d = 4^2 - 4 * 0.5 * 8
Evaluate
d = 0
The equation has only one real root since the discriminant is 0,

If for the slower printer it takes 10 hours for the whole thing, how much has it done in 1 hour? well, since it takes 10 hours total, in 1 hour it has only done 1/10 th of the whole work.
the faster printer however, can do it in 6 total, how much has it done in 1 hour? well, 1/6 of the whole work.
now, let's say, they both work together, and it takes "t" hours to finish the whole thing with both rolling.
let's add both rates to see how much that is,
which is 3 hours and 45 minutes.

Answer: x = -7.5
Solution:
3 x (-25) = x
Calculate
-7.5 = x
Swap the sides
x = -7.5
