SOLUTION: Perform the indicated operation: Problem 1 -3(a squared b squared + 3ab -3 +6ab +8 = -3 squared b squared + 9(ab) - 3 + 8 -3 squared b squared + 27ab +5 or would it be

Question 1164891: Perform the indicated operation:
Problem 1
-3(a squared b squared + 3ab -3 +6ab +8 =
-3 squared b squared + 9(ab) - 3 + 8
-3 squared b squared + 27ab +5
or would it be - 3 squared b squared + 9ab = 5
Is this correect?
Problem 2:
2xn(3xn + 2x +5) =
6xn + 4x +10 or would it be 2xn + 3xn +2x +5 = 5xn + 2x +5

Problem 3
Arrange in columns and add:
(x cubed - 64) + (3x squared - 2x +7
column 1 x cubed -64
column 2 3x squared
column 3 -2x +7
when added = -2x +x cubed + 3x squared -57
Thank you

-3(a squared b squared + 3ab -3 +6ab +8
If you mean:
= -3a^2b^2 + 3ab - 3 + 6ab + 8
= -3a^2b^2 + 9ab + 5
