Question

a2-b2=(a+b)(a-b) prove it

Answer 1

Answer:

Hey mate! Here's your answer:

Step-by-step explanation:

RHS = (a + b)(a - b)

a² + ab - ab + b²

a² - b² => LHS.

LHS = RHS, hence proved that a² - b² = (a + b)(a - b).

Answer 2

Answer:

(a^2-b^2 )= (a+b)(a-b)

Step-by-step explanation:

let a =1/2 , b=1/3

a+b=5/6

a-b =1/6

(a+b)(a-b)=5/36   .....(1)

a^2= 1/4

b^2=1/9

a^2-b^2= 1/4-1/9 =5/36......(2)

from(1) and(2)

it is proved that a^2-b^2 = (a+b)(a-b)
