Answer:
Step-by-step explanation:
well... all the least common factor have to write in the increasing order.
So, following this picture, we have to write in this order:
2 x 2 x 2 x 3 x 5
Das is difference of 2 perfect squares
remember
a^2-b^2=(a-b)(a+b)
so
25x^4=(5x^2)^2
16y^2=(4y^2)
(5x^2)^2-(4y)^2=(5x^2-4y)(5x+4y)
cannot be factored further
Two different teaching methods would be visual learning and written learning
