Which expression is equivalent to x^4– 8x^2 + 16 1) (x^2 + 4)(x² + 4)
2) (x^2 – 4)(x^2 – 4)
3) (4-x^2)(4+x^2)
4) (x^2 + 4)(x² – 4)

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
