Question

verify the following for a= 3 and b= 4
c)(a + b) (a - b) = a² - b²​

Answer 1

Step-by-step explanation:

a = 3 b = 4

(3+4)(3-4) = 9-16

7(-1) = -7

-7 = -7

Thus, proved

Answer 2

Answer:

The above statement is true L.H.S=R.H.S

Step-by-step explanation:

L.H.S

(a+b)(a-b)

(3+4)(3-4)

(7)(-1)

-7

R.H.S

a^2-b^2

(3)^2-(4)^2

9-16

-7

L.H.S=R.H.S

Hence Proved
