The correct Answer is:
To find the quotient and remainder when dividing \(2x^3 - 5x^2 + 8x - 5\) by \(2x^2 - 3x + 5\), we will use polynomial long division. Here’s the step-by-step solution: ### Step 1: Set up the division We will divide \(2x^3 - 5x^2 + 8x - 5\) (the dividend) by \(2x^2 - 3x + 5\) (the divisor). ### Step 2: Divide the leading terms Divide the leading term of the dividend \(2x^3\) by the leading term of the divisor \(2x^2\): \[ \frac{2x^3}{2x^2} = x \] This gives us the first term of the quotient. ### Step 3: Multiply and subtract Now, multiply the entire divisor \(2x^2 - 3x + 5\) by \(x\): \[ x(2x^2 - 3x + 5) = 2x^3 - 3x^2 + 5x \] Next, subtract this result from the original polynomial: \[ (2x^3 - 5x^2 + 8x - 5) - (2x^3 - 3x^2 + 5x) = (-5x^2 + 3x^2) + (8x - 5x) - 5 \] This simplifies to: \[ -2x^2 + 3x - 5 \] ### Step 4: Repeat the process Now, we will divide the new leading term \(-2x^2\) by the leading term of the divisor \(2x^2\): \[ \frac{-2x^2}{2x^2} = -1 \] This gives us the next term of the quotient. ### Step 5: Multiply and subtract again Multiply the entire divisor by \(-1\): \[ -1(2x^2 - 3x + 5) = -2x^2 + 3x - 5 \] Subtract this from the current polynomial: \[ (-2x^2 + 3x - 5) - (-2x^2 + 3x - 5) = 0 \] ### Step 6: Conclusion Since the remainder is \(0\), we conclude that the division is exact. Thus, the quotient is: \[ \text{Quotient} = x - 1 \] And the remainder is: \[ \text{Remainder} = 0 \] ### Final Answer: - Quotient: \(x - 1\) - Remainder: \(0\)
