When you differentiate, the constant disappears, because it is not dependent of the variable. So when you integrate, you have to add the constant again. However, you can't know the vaulue of c without ...

For all quadratic equations, you can use the quadratic formula. Given an equation of the form ax²+bx+c, you can plug those va...

Pythagoras' Theorem states that h² = a² + b² . This is where you have...

P(2 orange sweets) = P(orange sweet) * P(orange sweet)

(6/n) * (5/(n-1)) = 1/3

30/(n(n-1)) = 1/3

90 = n(n-1)

90 = n²-n

The quadratic formula is a way of solving quadratic equations of the form: ax²+bx+c=0. By plugging in the values a,b and c into it, the solutions for x can be obtained:x = [-b +/- sqrt(b^2<...
