Answer 2

heya

as i m in 9th so i can tell u 9th formula's. these are

1/2(x+y) let d=(y-x)/(n+1) (for find rational numbers)
OB= ROOT(OA^2+AB^2)
OC= root(OB^2+BC)
OD= root(OC^2+CD^2) for represent number on real line.
root(ab) = root(a)× root(b).

a^q×a^p= a^q+p for simplify.

(x+y)^2 = x^2+y^2+2xy for factorize

a^2-b^2= (a+b) (a-b) for sq. factorize

(x+y+z)^2= x^2+y^2+z^2+2xy+2yz+2zx for sy. of a trinomial.
a-b^2= a^2-2ab+b^2 for evalute.


there are many more but cant write all.

thank u
