How to Use a Scientific Calculator for Algebra?

TopFor handling complex problems in field of science especially in engineering physics and mathematics we have an electronically designed device called as scientific calculator.
Graphing Calculators are reducing the usage of scientific calculators in certain perspectives such as higher education, offering many other features like the ability to graph the input data and write and store programs with usual functionality of scientific calculators. Financial Calculators are also trying to make space I the market.

Various functions are provided to understand how to use a scientific calculator for Algebra:
Generally scientific calculators are more featured than standard four or five-function calculator, and this difference is clearly seen in the type of manufacturers and models; however, the main features of scientific calculators are:
scientific notation
Arithmetic including floating Point numbers
logarithmic functions
trigonometric functions
exponential functions
roots can be calculated other than Square root
quick access to constants like P and e

The highly equipped scientific calculators may also have these features:
hexadecimal, binary, and octal calculations and conversions
Boolean algebra functions
Solving complex Numbers and Fractions
statistics and Probability calculations
Solving complex equations
calculus

Uses of scientific calculators:
Quick access to mathematical functions is possible with scientific calculators, functions like those related to Trigonometry; the situations involving direct calculations of very large numbers (such as in contexts of astronomical calculations). In schools also the use of scientific calculators is a usual thing, having solved the problems of maths and physics.
An Example can be taken to understand the use of scientific calculators:
Q.For example, how would you solve 10 = x^2 + 3*(x ^1) using scientific calculator?
Solution: All the above used operations are present in the scientific calculators which directly calculate the value of ‘x’ solving the algebraic equation:
x ^ 2 + 3* (x ^1) – 10= 0
x = 5 or -2
