Too good Works perfectly using shreedharacharya's formula. There is only one problem that it does not show alternative methods for solving the equation. For instance, it does not show the steps for solving the equation using middle term factorisation. However, respect for the developer. Thanks for helping all users out.

Awesome app The stars would become five if u answer this question, how does this caculator take the square root of negative numbers!? We cannnot take the square of negative numbers it is an error . Answer to these types of questions is "complex". Pls fix this problem.......Overall its a very useful app, salute to the producers!!!.

Can't use scientific notation Worthless for anything other than simple quadratic equations. Useless in science class. Can't use really big or really small numbers.

Works quickly with no fuss Displays complex numbers in full workings. Technically the mathematical notation is to use j as the imaginary number, but that is not affecting the app in any fashion.

Ads Is there a way I can pay you to turn the ads off? Please make a paid version - I'd be willing to give a buck or two.

The square root of a negative number can be expressed using imaginary numbers (https://en.wikipedia.org/wiki/Imaginary_number). The app does support this. Very useful It helps me a lot with my pre-cal work and it is amazing high- five to the developers

Best Really good. Very useful. Quick Answers. No shit. Everyone who has problems with middle terms USE THIS APP

Can't expect better from a 0.4 mb app! Very useful for students.

Impressive Works, doesn't even ask for Internet access, or the rest of those annoying permissions...

I hate it Is only one ecuation and you can't wrote what ecuation you want

Awesome app Really helpful, would love to see it increase the type of equations, so it can solve cubics etc

Wrong answers Most of the answers I got from here were completely wrong

The Best App Ever This app helped me so much on my homework, I was surprised I had some answers right it helped me so much to go over my work

Amazing app! It shows step by step how to solve the problems

AMAZING APPLICATION! MUST DOWNLOAD This spectacular app will help you on your math homework and it's basically a guaranteed 100

Great app It shows all the steps……… great app calvico keep up the good work

Amazing app You just have to put the coefficients and and the roots are in front of you. Loved it.

Amazing First review I've ever done . it's spectacular . works as it should and its generally really good. Not much else to. Say

Need X^3 please The app is gold but it does not have x ^3... please add that too
