Description by K. Dev (from Google Play)

This is a smart application which solves quadratic equations or formulas and gives you the step-by-step solution. Unlike most of the other apps, this app is featured with both "Quadratic Formula" and "Completing the square" methods.

★ Capable of generating graphs for a given equation.

★ Both "Quadratic Formula" and "Completing the square" methods available.

★ Ability to save step-by-step solution as an image.

★ User friendly interface with Material design.

★ Decimal and fractional number inputs.

★ Decimal and fractional number output.

★ Handles imaginary numbers.

★ Each variable input is a simple calculator supporting the following operators ( *, /, +, -).

★ Lightweight.

NOTE : Quadratic equations are of the form ax2+bx+c=0 where a, b and c are real numbers and "a" should not be equal to zero. Quadratic equations have two solutions. It is possible that one solution may repeat. You can calculate quadratic equations by Completing the square and by Quadratic Formula.

Solving by Competing the Square

• Keep all terms containing x on one side. Move the constant to the right.

• Get ready to create a perfect square on the left. Balance the equation.

• Take half of the x-term coefficient and square it. Add this value to both sides.

• Simplify and write the perfect square on the left.

• Take the square root of both sides. Be sure to allow for both plus and minus.

• Solve for x.

Solving by Quadratic Formula

The solutions of some quadratic equations are not rational, and cannot be factored. For such equations, the most common method of solution is the quadratic formula. The quadratic formula can be used to solve ANY quadratic equation.

Comments on Quadratic Equation Solver for Android

★★★★☆ Anita Singh · Sep 4, 2021

It is good app but your solver is giving me wrong answers Like 35x²–20x–15 Here (7x+3)(5x–5)=35x²–20x–15 So zeroes are (X)first zero=–3/7 (X)second zero=5/5 So in second case it is giving zero value=1 And rounded off 5 So I used zeroes to find equation; (7x+3)(x–1) Which was=7x²–2x–3 But my equation was =35x²–20x–15 So has he eaten 5? If so then what if instead of eating 5 He eats (-1) Then this will be serious issue Because;; (-7x+3)(-x+1)=(7x-3)(x-1)

★★★★★ Abubakar Meraj · Dec 5, 2022

This app is the one of the best, but it is the only best solver ever I found. I love its feature of explaining the steps

★★★★★ kim Pangit · Sep 27, 2022

Its amazing Itsssss Sooo goodd to use in math and math classes and homework

★★★★★ SURAJ Rocks · Dec 29, 2021

Good aap for saving time from these shots called quadratic equations

★★★★★ CHERRY ALIMENTO · Nov 2, 2021

It really helps my son to answer his quadratic equation lessons. Especially his homework about problem-solving

For such a small task they're giving ads. That too not on mute. Ads start loudly in the middle of nowhere
