Hello frndz,
Today we will start with Algebra... First know about introduction of Algebra.
:- Algebra is based on a set of combination of variable and operations performed on that.
For eg. x+5 is an algebraic expression.
:- In expression 19x^2 - 6x + 3; 19 is the coefficient of x^2, -6 is the coefficient of x and 3 is a constant term.
:- When working with algebraic expressions, it is necessary to simply them by factoring or combining like terms.
For eg. 6x + 5x = (6 + 5)x = 11x
:- Simply (3xy - 9y) / (x - 3)
3y(x - 3) / (x - 3) = 3y
:- To multiply two algebraic expressions, each term of one expression is multiplied by each term of the other expression.
For eg. (3x - 4)(9y + x)
3x (9y + x) - 4 (9y + x) = 3x * 9y + 3x * x - 4 * 9y - 4 * x
= 27xy + 3x^2 - 36y - 4x
The given expression can be evaluated by substituting values of variables in the expression.
For eg. If x=3 and y=-2
then above expression can be evaluated as
27(3)(-2) + 3(3)^2 - 36(-2) - 4(3)
= -162 + 27 + 72 - 12
= -75
Okie guys, Keep practice on!!!

Is there a calculator that will simplify algebric equations?
ReplyDeleteWondering if there reallly is a calculator that will solve any algebra equations ? I don't think there is but friends of mine have told me there is one. Thanks for your answer there is a chocolate cake riding on this.
Sorry Nick,
ReplyDeleteNo calculator can simplify algebraic expressions. You need to learn tricks and tips to do so.....
i think there is algebraic expressions simplifier calculator, just googling.:)
