(a+b)2=a2+2ab+b2
(a-b)2=a2-2ab+b2
(a+b)(a-b)=a2-b2
these are the standard identities
another one:
(x+a)(x+b)=x2+(a+b)x+ab

What is algebraic expressions and identities?
they are the simple rules in algebra which make calculations a lot easier
Why do you use standard form in algebra?
You use standard form in algebra because you have to know the number before you answer the problem
How do you write standard form in math?
Well, if we're talking algebra, then standard form is ax+by=c
What is regular maths and general maths for tenth standard?
It depends a little on where you are attending school and what courses you have already completed. Usually, Geometry is standard for 10th graders. You usually take geometry after you take Algebra 1 in 9th grade. However, I took Algebra 1 in 8th grade, Geometry in 9th, and Algebra 2 in 10th. So, if you're a little behind in math, you might take Algebra 1. If you're average, you might take Geometry. If you're ahead, you might take Algebra 2.
What are identities in algebra?
An equation in which the variable(s) can take any value and it is still true. ex. cos(x) = cos(-x) sin(x) = -sin(-x) The above equations are true for any real value of x. Identities are sometimes written with a "triple equals sign", as in 3 parallel lines rather than 2.

Who invented special products as identities?
The concept of special products as identities in mathematics was not invented by a single individual. It is a fundamental principle in algebra that describes certain algebraic patterns or expressions that simplify into known equations or forms, such as the binomial theorem or the difference of squares.

How can you make good marks in maths calculus?
Know you algebra and trig. When I took calculus that is what my teachers told me. You will use both extensively in manipulations and identities and functions. Then you can learn the calculus.

How do I know if I need a scientific or standard calculator?
Standard works on simple math problems if you are doing algebra or above get a scentific and it will work on basic problems too.
I'm a college student and I'm taking a Pre calculus class at school this fall. What are main topics in Algebra and Trig that I should firmly know walking into class?
It would help to know both quite well - they are really not that complicated. But actually, in the case of algebra, you just need the basics - simple things like simplifying expressions, and solving equations. In the case of trigonometry, you may want to concentrate on the trigonometric identities. If you can't memorize all of them, don't worry; you will be reminded of the relevant identities in the calculus course.
In maths What is an identity?
An identity is a set of two (or more) quantities that are identical in every single way. Trigonometry is famous for identities. Two examples include: cos (-x) = cos x and sin (-x) = -sin x The values on either side of the equal sign are in every way the same exact thing, and thus, these are identities. Solving trigonemtric algebra problems requires the often clever use of complex identities, and many seemingly unsolvable problems are solved in this way.
