The discriminant helps us determine the nature of the roots of a quadratic equation
When using the quadratic formula the find the roots of a quadratic equation, the term (b²-4ac) is known as the discriminant.
Where b ⇒ coefficient of the 2nd term
a ⇒ coefficient of the 1st term
c ⇒ the 3rd term.
In the equation 3x²-6x+5, the discriminant is;
(-6)² - (4×3×5) = 36 - 60
= -24

Lets focus on what we know first. Natalie can pick 135 Berries in 15 minutes. Lets find out how many berries she can pick per minute.
In order to do so, We have to divide 135 by 15.
135/15=9
This means that Natalie can pick 9 berries per minute. Given that we want her to pick 486, we will need to divide that number by 9 berries to find out how many minutes it will take to get her to that number of berries.
486/9=54
This means that it will take Natalie 54 minutes in order to pick 486 berries.
