Where
a1, b1, c1, a2, b2, and c2 are all real numbers and
a12+b12 ¡Ù 0 & a22 + b22 ¡Ù 0
It should be noted that linear equations in two variables
() can also be
represented in graphical form.
Algebra or Elgebraic Equations
The standard form of Quadratic Equations:
ax2+bx+c=0 where a ¡Ù 0
And x = [-b ¡À ¡Ì(b2 ¨C 4ac)]/2ac
Algebraic formulas:
(a+b)2 = a2 + b2 + 2ab
(a-b)2 = a2 + b2 ¨C 2ab
(a+b) (a-b) = a2 ¨C b2
(x + a)(x + b) = x2 + (a + b)x + ab
(x + a)(x ¨C b) = x2 + (a ¨C b)x ¨C ab
(x ¨C a)(x + b) = x2 + (b ¨C a)x ¨C ab
(x ¨C a)(x ¨C b) = x2 ¨C (a + b)x + ab
(a + b)3 = a3 + b3 + 3ab(a + b)
(a ¨C b)3 = a3 ¨C b3 ¨C 3ab(a ¨C b)
(x + y + z)2 = x2 + y2 + z2 + 2xy + 2yz + 2xz
(x + y ¨C z)2 = x2 + y2 + z2 + 2xy ¨C 2yz ¨C 2xz
(x ¨C y + z)2 = x2 + y2 + z2 ¨C 2xy ¨C 2yz + 2xz
(x ¨C y ¨C z)2 = x2 + y2 + z2 ¨C 2xy + 2yz ¨C 2xz
x3 + y3 + z3 ¨C 3xyz = (x + y + z)(x2 + y2 + z2 ¨C xy ¨C yz -xz)
x2 + y2 =? [(x + y)2 + (x ¨C y)2]
(x + a) (x + b) (x + c) = x3 + (a + b +c)x2 + (ab + bc + ca)x + abc
x3 + y3= (x + y) (x2 ¨C xy + y2)
x3 ¨C y3 = (x ¨C y) (x2 + xy + y2)
x2 + y2 + z2 -xy ¨C yz ¨C zx = ? [(x-y)2 + (y-z)2 + (z-x)2]

Arithmetic Progression(AP) Formulas
If a1, a2, a3, a4, a5, a6,¡ are the terms of AP and d is the common difference
between each term, then we can write the sequence as; a, a+d, a+2d, a+3d, a+4d,
a+5d,¡.,nth term¡ where a is the first term. Now, nth term for arithmetic
progression () is given as;
nth term = a + (n-1) d
Sum of nth term in Arithmetic Progression;
Sn = n/2 [a + (n-1) d]
