Solving absolute value equations and inequalities. And represents the distance between a and 0 on a number line. An absolute value equation is an equation that contains an absolute value expression. Has two solutions x = a and x = -a because both numbers are at the distance a from 0. Absolute Equation

Algebraic Fraction
This post about Algebraic fractions are a fraction whose numerator and denominator are algebraic expressions. Fractions in Algebra. We can add, subtract, multiply and divide fractions in algebra in the same way we do in simple arithmetic. Adding Fractions. When adding or subtracting algebraic fractions, the first thing to do is to put them onto a common denominator (by cross multiplying). Therefore we solve by […]
Sequence-2
Sequence and series is arrangement of term in particular pattern. Mathematical structures using the convergence properties of sequences. In particular, sequences are the basic for series Sequence and series
Expansion
Expansions of Algebraic Expressions The formula: a(b+c) = ab + ac Algebraic Expansion. (a+b)(c+d)=ac+ad+bc+bd and (a+b)(a-b)= a ² – b² difference of square (a+b)² = a² + 2ab + b² perfect square (a-b) ²=a²-2ab+b² Expansion
Factorisation
Factorisation process we applied bracket to take common term out. Also we apply difference of square of variable. Hence we reduce no of terms in expression. Therefore factorisation and expansion are reverse process. Factorisation
Simultaneous Eq.
simultaneous equations are solve by the elimination. These equations are also solve by substitution as well as graphic method. Due to variable solution give coordinate. simultaneous equation
Angle Properties
The total angle at a point is 360 ° w +x+y+z=3600. 2. The total angle on a straight line is 180 ° In the diagram, x+y+z=1800 3. When two straight lines cross, vertically opposite angles are equal. In the diagram, • angles a and c are equal, • angles b and d are equal. Angle […]

Linear inequation
Solve linear inequalities is like solving linear equations with with inequality sign. Due to inequality sign its graph is area. Also it give dark line and dotted line. Linear inequation
