Question

simplify 322*322-2*322*22+22*22

Answer 1

Again, let 322=a
22=b
Then the equation becomes
a^2-2ab-b^2
This is the formula for (a-b)^2
Substituting values of a and b
(322-22)^2
=300^2
=90000

Answer 2

Step-by-step explanation:

Given,

322×322−2×322×22+22×22

=322

2

−2×322×22+22

2

By using (a−b)

2

=a

2

+b

2

−2ab

=(322−22)

2

=300

2

=90000
