Question

10 algebric identities pls tell me

Answer 1

Identify :- An Identity is a equation for which any value should be satisfied by the variables.

a²-b²=(a+b)(a-b)

(a+b)²=a²+b²+2ab

(a-b)²=a²+b²-2ab

a³-b³=(a-b)(a²+b²+ab)

a³+b³=(a-b)( a²+ b²-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)

(a+1)²=a²+1+2a

(a+b+c)²=a²+b²+c²+2(ab+bc+ca)

Answer 2

Hello friend

Here are 10 algebric identities

• (a+b)²=a²+2ab+b²

• (a-b)²=a²-2ab+b²

• a²-b²= (a+b)(a-b)

• a³+b³=(a+b)(a²-ab+b²)

• a³-b³=(a-b)(a²+ab+b²)

• (a+b)³=a³+b³+3ab(a+b)

• (a-b)³=a³-b³-3ab(a-b)

• (a+b+c)²=a²+b²+c²+2ab+2bc+2ca

• a³+b³+c³-3abc= (a+b+c)(a²+b²+c²-ab-bc-ca)

•(x+a)(x+b)=x²+x(a+b)+ab

Hope it helps!
