Question

B(b-3c)-(b-3c) как решить?

Answer 1

Это ответ
${b}^{2} - 3bc - d + 3c$

Answer 2

To solve the expression B(b-3c)-(b-3c), you can follow these steps:

Step 1: Identify like terms (terms that have the same variables raised to the same powers) within the expression.

In this case, the like terms are B(b-3c) and -(b-3c) since they both contain the term (b-3c).

Step 2: Perform the operations within the parentheses.

Inside the first parentheses (b-3c), you cannot perform any further operations since it is already simplified.

Inside the second parentheses -(b-3c), you can distribute the negative sign to both terms inside the parentheses:

-(b) - (-3c) = -b + 3c

Step 3: Replace the original expression with the simplified terms.

Now, the expression becomes:

B(b-3c) - (b-3c) = B(b-3c) - b + 3c

And that's the final simplified expression. It cannot be simplified any further since there are no more like terms to combine.
