Question

Simplify (4.5p – 3.5q)²– (4.5p – 3.5q)²​

Answer 1

answer:- 0

4.5q- 3.5q = 1q

then 1square is 1

then 1 - 1

0

Answer 2

Answer:

Answer is 0

Step-by-step explanation:

(4.5p - 3.5q)²-(4.5p - 3.5q)²

=(4.5p - 3.5q + 4.5p -3.5q) (4.5p - 3.5q - 4.5p +3.5q)      [As a²-b²=(a+b)(a-b)]

=(4.5p - 3.5q + 4.5p -3.5q)0

=0

Or,

(4.5p - 3.5q)²-(4.5p - 3.5q)²

= x - x                                              [Let x = (4.5p - 3.5q)²]

=0

Hope it help :)
