Drag and drop the expressions into the boxes to correctly complete the proof of the polynomial identity. (x2−y2)2+x4+y4=2(x4−x2y2+y4) (x2−y2)2+x4+y4=2(x4−x2y2+y4) Response area+x4+y4=2(x4−x2y2+y4) Response area=2(x4−x2y2+y4) Response area=2(x4−x2y2+y4)

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
