1. IMPORTANT MATHS FORMULAE

   Algebra:

   1. (a + b)2 = a2 + 2ab + b2
   2. (a – b)2  = a2 – 2ab + b2
   3. (a + b) (a – b) = a2 – b2
   4. (x + a)(x + b)  = x2 + (a + b)x + ab
   5. (x + a)(x – b)  = x2 + (a – b)x – ab
   6. (x – a)(x + b)  = x2 + (b – a)x – ab
   7. (x – a)(x – b)  = x2  – (a + b)x + ab
   8. (a + b)3  = a3 + b3 + 3ab(a + b)
   9. (a – b)3  =  a3 – b3 – 3ab(a – b)
   10. (x + y + z) 2  = x2 + y2 + z2 + 2xy + 2yz + 2xz
   11. (x + y – z) 2  =  x2 + y2 + z2 + 2xy – 2yz – 2xz
   12. (x – y + z)2  = x2 + y2 + z2 – 2xy – 2yz + 2xz
   13. (x – y – z)2  = x2 + y2 + z2 – 2xy +  2yz – 2xz
   14. x3 + y3 + z3 – 3xyz  = (x + y + z)(x2 + y2 + z2 – xy – yz -xz)
   15. x2 + y2  = 1212 [(x + y)2 + (x – y)2]
   16. (x + a) (x + b) (x + c) = x3 + (a + b +c)x2 + (ab + bc + ca)x + abc
   17. x3 + y3 = (x + y) (x2 – xy + y2)
   18. x3 – y3  = (x – y) (x2 + xy + y2)
   19. x2 + y2 + z2 -xy – yz – zx = 1212 [(x-y)2 + (y-z)2 + (z-x)2]

   Powers:

   amxan  = am+n

   aman=am−naman=am−n

   (am)n  =  amn

   (ambn)p =   ampb np

   a-m = 1am1am

   amn=am−−−√namn=amn

   Rules of Zero:

   a1  = a

   a0 = 1

   a*0 = 0

   a is undefined

   Linear Equation:

   Linear equation in one variable ax + b = 0, x = – −ba−ba

   Quadratic Equation:  ax2 + bx + c  = 0  x  = −b±b2−4ac√2a−b±b2−4ac2a

   Discriminant D = b2 – 4ac

   Math Formulas:

   When 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
