Answer:
With a discriminant of 25,the function has two solutions,
+5 and -5.
Step-by-step explanation:
Consider the solutions to the quadratic equation:
ax² + bx + c = 0
The solution, which is the quadratic formula:
x = [-b ± √(b² - 4ac)]/2a
The value
D = b² - 4ac
is called the discriminant.
If a function has a discriminant of 25, note that in the quadratic formula, we have
D = b² - 4ac = 25
√D = ±√25 = ±5
This means there would be two solutions for the quadratic equation.
