Quickly compute the following differences of squares. (a). 64^2 − 14^2 (b). 112^2 − 88^2 (c). 785^2 − 215^2
VikaD [51]

Answer:

(a) 3900

(b) 4800

(c) 570000

Step-by-step explanation:

We have given

(a) 64^2-14^2

We know the algebraic equationa^2-b^2=(a+b)(a-b)

So 64^2-14^2=(64+14)(64-14)=3900

(b) We know the algebraic equationa^2-b^2=(a+b)(a-b)

112^-88^2=(112+88)(112-88)=4800

(c) We know the algebraic equationa^2-b^2=(a+b)(a-b)

785^2-215^2=(785+215)(785-215)=570000
