EQUATIONS


  1. Linear Equation :
  2. A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable. Linear equations can have one or more variables. 
4P+8Q=3---(1)
12P+4Q=4---(2)

Solve (1)
(1)*3=12P+24Q=9---(3)

Solve (2) and (3)
12P+24Q=9
12P+4Q=4
20Q=5
Q=1/4---(4)

Put (4) any ()equations
4P+8*(1/4)=3
4P+2=3
4P=1
P=1/4

Relation ship Between P and Q
1/4=1/4
P=Q




    Quadratic Equation:
  1. The Quadratic Formula is derived from the process of completing the square, and is formally stated as: For ax2 + bx + c = 0, "(quadratic) = 0".


  2. Relation Ship Between X1 and X2
  3. 5>2
  4. X1>X2
