Question

30xy-2xy=?
help do help​

Answer 1

Step-by-step explanation:

Simplifying

-2xy(-30xy) = 0

Remove parenthesis around (-30xy)

-2xy * -30xy = 0

Reorder the terms for easier multiplication:

-2 * -30xy * xy = 0

Multiply -2 * -30

60xy * xy = 0

Multiply xy * xy

60x2y2 = 0

Solving

60x2y2 = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '60'.

x2y2 = 0.0

Simplifying

x2y2 = 0.0

The solution to this equation could not be determined.
