Apr 16, 2020 · I honestly don't understand how this expression can be mathematically correct. I always end up writing x=+1 by accident because the correct way of writing seems so unintuitive to me. Reply …

Aug 9, 2013 · Factorize : $$ (x+1) (x+2) (x+3) (x+6)- 3x^2$$ I don't really know where to start, but I expanded everything to get : $$x^4 + 12x^3 + 44x^2 + 72x + 36$$ I used rational roots test and …

Aug 25, 2014 · If you can pretend you "guessed" the factorization, notice $ (x^2+5x+5)^2-1$ is a difference of squares.

18 Find line perpendicular to $ 2y=x+1$ which passes through $ (3, -3)$ Find intersection point of those two lines ( Foot of perpendicular ) Use Mid-Point Formula (special case of Section formula) to get …

Aug 17, 2014 · My base case is when n= 2 n = 2 we have on the left side of the equation x2 −1 x 2 1 and on the right side: (x−1)(x+1) (x 1) (x + 1) which when distributed is x2 −1 x 2 1.

Jan 26, 2017 · Ive solved this problem and both sides of the function don't appear to be equal to me. However the solution in the back of the book says it is a solution. Am I not simplifying enough? …

I am looking for the "best" way to determine whether a function is one-to-one, either algebraically or with calculus. I know a common, yet arguably unreliable method for determining this answer wou...

Aug 16, 2016 · How did you get your answer? Did you try to apply the chain rule? You might get better answers if you show your process so we can point out where things go wrong.

Feb 7, 2022 · Closed 3 years ago. Using the mean value theorem of lagrange I need to prove that for all x > 0: $$ \frac {1} {x+1} < ln (x+1) - ln (x) < \frac {1} {x} $$
