Question

If a=47 and b=3,verify that:(a+b) *(a-b) =a x a - b+b

Answer 1

Answer:

LHS = 2200

RHS = 2200

Step-by-step explanation:

One correction in question:

(a+b) *(a-b) = a*a - b*b

Given,

a = 47,

b = 3,

Then, the Equation

LHS = (a+b) *(a-b)

= (47+3)*(47-3)

=  50 * 44

=  2200

RHS = a x a - b*b

= 47*47 - 3*3

=  2209 - 9

= 2200

So, LHS = RHS Proved.
