The correct Answer is:
To remove the second term (the second higher power of \(x\)) from the equation \(x^3 - 6x^2 + 10x - 3 = 0\), we can use a substitution method. Here’s a step-by-step solution: ### Step 1: Write the original equation Start with the original equation: \[ x^3 - 6x^2 + 10x - 3 = 0 \] ### Step 2: Substitute \(x\) with \(y + a\) To eliminate the \(x^2\) term, we will make the substitution \(x = y + a\), where \(a\) is a constant we will determine later. Substitute this into the equation: \[ (y + a)^3 - 6(y + a)^2 + 10(y + a) - 3 = 0 \] ### Step 3: Expand the equation Now, expand the equation: \[ (y^3 + 3ay^2 + 3a^2y + a^3) - 6(y^2 + 2ay + a^2) + 10y + 10a - 3 = 0 \] This simplifies to: \[ y^3 + 3ay^2 + 3a^2y + a^3 - 6y^2 - 12ay - 6a^2 + 10y + 10a - 3 = 0 \] ### Step 4: Collect like terms Now, group the terms by their powers of \(y\): \[ y^3 + (3a - 6)y^2 + (3a^2 - 12a + 10)y + (a^3 - 6a^2 + 10a - 3) = 0 \] ### Step 5: Set the coefficient of \(y^2\) to zero To eliminate the \(y^2\) term, set the coefficient of \(y^2\) to zero: \[ 3a - 6 = 0 \] Solving for \(a\): \[ 3a = 6 \implies a = 2 \] ### Step 6: Substitute \(a\) back into the equation Now substitute \(a = 2\) back into the equation: \[ y^3 + (3(2)^2 - 12(2) + 10)y + (2^3 - 6(2^2) + 10(2) - 3) = 0 \] Calculating the coefficients: - For \(y\): \[ 3(4) - 24 + 10 = 12 - 24 + 10 = -2 \] - For the constant term: \[ 8 - 24 + 20 - 3 = 1 \] ### Step 7: Write the final equation Thus, the equation simplifies to: \[ y^3 - 2y + 1 = 0 \] This equation does not contain the second power of \(y\), which means we have successfully removed the second term. ### Final Answer: The transformed equation is: \[ y^3 - 2y + 1 = 0 \] ---
