Algebra:
 (a + b)^{2} = a^{2} + 2ab + b^{2}
 (a – b)^{2} = a^{2} – 2ab + b^{2}
 (a + b) (a – b) = a^{2} – b^{2}
 (x + a)(x + b) = x^{2} + (a + b)x + ab
 (x + a)(x – b) = x^{2} + (a – b)x – ab
 (x – a)(x + b) = x^{2} + (b – a)x – ab
 (x – a)(x – b) = x^{2} – (a + b)x + ab
 (a + b)^{3} = a^{3} + b^{3} + 3ab(a + b)
 (a – b)^{3} = a^{3} – b^{3} – 3ab(a – b)
 (x + y + z)^{ 2 } = x^{2} + y^{2} + z^{2} + 2xy + 2yz + 2xz
 (x + y – z)^{ 2 } = x^{2} + y^{2} + z^{2} + 2xy – 2yz – 2xz
 (x – y + z)^{2} = x^{2} + y^{2} + z^{2} – 2xy – 2yz + 2xz
 (x – y – z)^{2} = x^{2} + y^{2} + z^{2} – 2xy + 2yz – 2xz
 x^{3} + y^{3} + z^{3} – 3xyz = (x + y + z)(x^{2} + y^{2} + z^{2} – xy – yz xz)
 x^{2 }+ y^{2} = 1212 [(x + y)^{2} + (x – y)^{2}]
 (x + a) (x + b) (x + c) = x^{3 }+ (a + b +c)x^{2} + (ab + bc + ca)x + abc
 x^{3} + y^{3} = (x + y) (x^{2 }– xy + y^{2})
 x^{3} – y^{3} = (x – y) (x^{2 }+ xy + y^{2})
 x^{2 }+ y^{2 }+ z^{2 }xy – yz – zx = 1212 [(xy)^{2 }+ (yz)^{2 }+ (zx)^{2}]
Powers:
a^{m}xa^{n} = a^{m+n}
aman=am−naman=am−n
(a^{m})^{n} = a^{mn}
(a^{m}b^{n})^{p} = a^{mp}b ^{np}
a^{m} = 1am1am
amn=am−−−√namn=amn
Rules of Zero:
a^{1} = a
a^{0} = 1
a*0 = 0
a is undefined
Linear Equation:
Linear equation in one variable ax + b = 0, x = – −ba−ba
Quadratic Equation: ax^{2 }+ bx + c = 0 x = −b±b2−4ac√2a−b±b2−4ac2a
Discriminant D = b^{2 }– 4ac
Simple Interest:
When the rate of discount is given Discount = MP∗Rate of Discount 100
Simple Interest = PTR100PTR100 where P = Principal, T = Time in years R = Rate of interest per annum
Principal = 100∗S.IR∗T100∗S.IR∗T
Rate = 100∗S.IP∗T100∗S.IP∗T
Time = 100∗S.IP∗R100∗S.IP∗R
Principal = Amount – Simple Interest
Discount = MP – SP
Trigonometry:
Probability
P(E) = Number of outcomes favorable to E
Total Number of Possible Outcomes
