What is completely factored form of 25x4-16y2

(5x²+4y)(5x²-4y)

Step-by-step explanation:

25x4 -16y2 looks like the the difference of two sqaures where everything to be factorized has a square root.

Let's try and reduce it , so we'll understand.

25x4 -16y2 = 5x²5x² - 4y4y

Factorizing the more gives us

= (5x²+4y)(5x²-4y)

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

the diameter is 16 cm. are you a teacher?
