Question

evaluate the following product by using suitable identities ​

Answer 1

Answer:

given

=(116)^2-(106)^2

so, (116-106)×(116+106)

=10×222

=2220

Answer 2

a) (116)^2 - (106)^2

(116+106)(116-106)

222 × 10

=2220.

b) (4)^2 + (5X)^2 - 2×4×5X

16 + 25X^2 - 40 X

= 25X^2 - 40X + 16

C) (X)^3 - (2)^3 - 3(X)^2(2) + 3(X)(2)^2

X^3 - 8 - 6X^2 + 12X

= X^3 - 6X^2 + 12X - 8
