To simplify the polynomial expression \((2x−3)(x^2−4x+5)\), we will use the distributive property (often called the FOIL method for binomials). We will distribute \(2x\) and \(-3\) to each term inside the second polynomial.

  1. Distributing \(2x\):

    • \(2x \cdot x^2 = 2x^3\)
    • \(2x \cdot (-4x) = -8x^2\)
    • \(2x \cdot 5 = 10x\)
  2. Distributing \(-3\):

    • \(-3 \cdot x^2 = -3x^2\)
    • \(-3 \cdot (-4x) = 12x\)
    • \(-3 \cdot 5 = -15\)

Now we combine all these results together: \[ 2x^3 - 8x^2 + 10x - 3x^2 + 12x - 15 \]

Now combine like terms:

  • The \(x^3\) term is \(2x^3\).
  • The \(x^2\) terms: \(-8x^2 - 3x^2 = -11x^2\).
  • The \(x\) terms: \(10x + 12x = 22x\).
  • The constant term is \(-15\).

So, the simplified polynomial expression is: \[ 2x^3 - 11x^2 + 22x - 15 \]

Based on the format asked in the question, the answer breaks down as follows:

  • \(x^3\) term: \(2\)
  • \(x^2\) term: \(-11\)
  • \(x\) term: \(22\)
  • Constant term: \(-15\)

Thus, the ultimately simplified polynomial is: \[ 2x^3 - 11x^2 + 22x - 15 \]
