Calculate the values of A, B, and C.
To solve this problem, we'll proceed with the following steps:
Now, let us work through these steps:
Step 1: Expand the expression .
Step 2: Substitute back into the equation and simplify by dividing by :
This simplifies to:
Step 3: To find , , and , compare coefficients of similar terms:
Therefore, the solution to the problem is that the values are .
Declares the given expression as a sum
\( (7b-3x)^2 \)
Use the formula . Here, and , so:
To compare coefficients properly! Split it as: . This matches the form on the left side.
Look at the constant terms! On the right side we have , on the left side there's no constant term (which means 0). So: , giving .
Match terms with the same powers of x! Compare:
Substitute back into the original equation! Left side: . Right side: . They match!
