If x+2 is a factor implies x=-2 is a solution

Sub in x=-2 : f(-2) = 6*(-2)³ + 13*(-2)² -4 = 6*-8 +13*4 - 4 = 0

f(-2) = 0 therefore x+2 is a solution

Solve by adding 16 to both sides of the equation yielding: x^2 = 16. Then take the square root of both sides (remembering that taking the square root gives us a positive and a negative answer), giving us ...

Let integrate be denoted by the letter I. For instance I(f) is the integration of a function f . Then Integration by parts states that I(u v') = uv - I(u' v), where u,v are function with u', v' their resp...

Picking 2 different types of storage would be a good start (i.e. not two different types of batteries; this way you have a little bit more to talk about as all storage types have their perks and setbacks)...

Okay so the first thing we can identify is that it is a quadratic, hence the x² at the beginning. From this we can now start to answer the question. To calculate the minimum po...
