Question

Which will result in a perfect square trinomial?
(3 x- 5)(3 x- 5)
(3 x-5)(5- 3 x)
(3 x-5)(3 x + 5)
(3 x- 5)(- 3 x-5)

Answer 1

Answer:

( 3x - 5 ) ( 3x - 5 )

9x^2 - 15 x - 15x + 25

9x^2 - 30x + 25

it is a perfect square trinomial

so , ( 3x - 5 ) ( 3x - 5 ) is right option .

hope it helps
