Question

tell me 10 formulas of any chapter of maths

Answer 1

Answer

D=bsq. -4ac

an=a+(n-1)d

Sn=n÷2(2a+(n-1)d)

x + a)(x + b) = x2 + (a + b)x + ab

(x + a)(x – b) = x2 + (a – b)x – ab

(x – a)(x + b) = x2 + (b – a)x – ab

(x – a)(x – b) = x2 – (a + b)x + ab

(a + b)3 = a3 + b3 + 3ab(a + b)

(a – b)3 = a3 – b3 – 3ab(a – b)

(x + y + z)2 = x2 + y2 + z2 + 2xy + 2yz + 2xz

Hope it helps..
