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.

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.

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!!!.

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.

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.

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

It's just great it does what it says. It doesn't need any unnecessary permissions and don't show any adds. It's always accurate and I always rely on it for my work to be done. I appreciate the developer for this creation & also suggest the developer to make more such apps.

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...

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

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

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

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

Great app Ignore the hate, this is amazing. Super useful for checking work.

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

Amazing I have intense respect for this developer. Good interface, great how it gives the work. Love it.

One of the best ones our there but numberpad it's difficult if you have a four inch phone

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

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

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

Really helps with quadratic equations especially when i get trying to solve an unsolvable one.

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

I think it's a great app but there needs to be an option to keep your answer into fraction form for college.

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

Splendid I love this tool it helps show HOW you got the problem solved

Finally found something that can help me on my homework.I think it it works really good!!!!!!!!

Great app! Shows work, step by step, including the discriminant! Very fast! Does outstanding job with imaginary roots!

excellent! very useful ...... always gives correct answers!

THE BEST Quickly solves quadratics no adds no internet connection required love the app

Improve it.. Like putting variables in place of cofficient of x.. Etc bugs
