Question 34484This question is from textbook Beginning and Intermediate Algebra

: (-3x cubed + y)(x squared - 8xy + 16y squared)
I get as far as -3x cubed + 25x squared y + 16y cubed
My book says it is -3x cubed + 25xsquared y - 56 xy squared + 16 y cubed
How did they find 56xy squared?
Any help would be appreciated.
