FACTORISE THE FOLLOWING: TYPE 1:- a2-b2 =(a+b)(a-b) Ex:- 1) x2-64 =x2-82 =(x+8)(x-8) TYPE 2:- splitting the middle term Method:- split the middle term in two terms so that- 1)Their...
R = Real Numbers: All rational and irrational numbers are called real numbers. I = Integers: All numbers from (…-3, -2, -1, 0, 1, 2, 3…) are called integers. Q = Rational Numbers: Real...
If two linear equations are given, then we can find the values of variables, by solving those equations simultaneously. 2x+3y=10---(1) x-3y=8-------(2) These are the two linear equations, we can find...
AREA OF THE RECTANGLE If Length of the rectangle = l Breadth(width) of the rectangle = b Then , formula to find the area of rectangle is given by A = l x b square units ...
When the sum of two angles=90 degrees, they are called complementary angles. We can use following formula →sin(90-θ)=cosθ,cos(90-θ)=sinθ,tan(90-θ)=cotθ,cosec(90-θ)=secθ,sec(90-θ)=cosecθ We...
