Different forms of the quadratic equation
A quadratic equation can be written in different forms forms: standard, factored, and vertex, each revealing different properties and solutions. Constants a, b, c affect the graph’s shape and position, while r1, r2, and h, k relate to roots and vertex coordinates.

What are quadratic equations?
In mathematics, equations like as linear, quadratic, and cubic describe relationships between variables. Quadratic equations have x squared as the highest power. Graphs help us visualize these relationships, and with given x values, y can be determined.

How to find the area of a shape
Just as the perimeter of a shape is like a fence, the area of a shape is like tiles. You need to find out many square tiles would fit in the shape since the unit is cm^2 or m^2. Once you know the formula for the area of a shape, you can apply it to…

How to name CARBOXYLIC ACIDS and write their formulas
Carboxylic acids are an organic compound. They are not hydrocarbons because they also contain O (Oxygen). Learn how to name them and write their molecular formulas and draw them.

What are polymers and how to draw them
A polymer is a structure made from many repeating units called monomers. In organic chemistry, you learn about many polymers that are plastics. For example, plastic bags and PVC are common polymers.

How to name and draw isomers of organic compounds
Alkanes of the same formula can have different arrangements of atoms. This is what isomers are. Learn how to find all the isomers of organic compounds and how to name the isomers and draw them.

Alkanes and alkenes combustion reactions (organic compounds – chemistry)
Combustion is when a substance is burnt in oxygen and produces CO2 and H2O. Learn about complete and incomplete combustion and how to write and balance the equations.

Bromine water test: How can we differentiate between alkanes and alkenes experimentally?
Alkanes and alkenes look and smell the same. So, you won’t know the difference unless you perform an experiment. This works because the reactions of alkanes and alkenes aren’t the same.

Alkenes and alkanes reactions (substitution and addition – organic chemistry)
Alkanes form part of substitution reactions whereas alkanes usually involves addition reactions. Learn all these reactions in one place with explanations in words, examples and formulas!
