Question

evaluate 99 square by using polynomial identities ​

Answer 1

Step-by-step explanation:

9. Calculate the perimeter of a rectangle whose area is 25x2 – 35x + 12. Use the method of splitting the middle term.

Answer 2

Answer:

(99) ^2=9801

(a-b) ^2=a^2+b^2-2ab

99 =100-1

99^2 =100^2+1^2-2(100)(1)

=10000+1-200

=9800+1

99^2 =9801
