thanks man I was searching for something like this for whole day

3. ## Re: Solving inequalities

can anyone help with this question please:
Use the addition property and/or multiplication properties to find a and b if:
-3<x<4 then a<x-5<b

Thank you. This will be very helpful!

6. ## Re: Solving inequalities

This is very helpful but i am still stuck on a particular inequality. 2-3x<|x-3|. So far i have used the modular property and obtained a three term quadratic equation which further factorizes to (2x+1)(4x-5)<0. So according to me the answer is -1/2<x<5/4 but according to the marking scheme its only x>-1/2. Can somebody plz explain why?

I was completely surprised by seeing all these meshes especially the triparts insert mesh.

Hello!
Solve the inequality $\displaystyle 3x^2+4ix+5<0$ , where $\displaystyle i^2=-1$.
Thank You!

I have trouble solving inequalities especially quadratic. My main problem is presenting critical points. I hope you attachment will solve my problem. Thank you

Any inequality can be written as an equation and so $\displaystyle ax^2+bx+c\leq 0$ you can write the equation as $\displaystyle ax^2+bx+c=d\leq 0$.The solutions of the inequality are :

$\displaystyle x=\frac{-b\pm \sqrt{b^2-4a(c-d)}}{2a}$ where $\displaystyle d\leq 0$.
