Question

Expand: (3ab + 4cd) (3ab + 4cd)​

Answer 1

Answer:

Simplifying

3ab + 4cd = 0

Solving

3ab + 4cd = 0

Solving for variable 'a'.

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

Add '-4cd' to each side of the equation.

3ab + 4cd + -4cd = 0 + -4cd

Combine like terms: 4cd + -4cd = 0

3ab + 0 = 0 + -4cd

3ab = 0 + -4cd

Remove the zero:

3ab = -4cd

Divide each side by '3b'.

a = -1.333333333b-1cd

Simplifying

a = -1.333333333b-1cd
