  1. Recognize and Determine Factoring Strategy: Recognize the type of polynomial and determine the factoring strategy.\newlineThe given polynomial is a quadratic in the form of ax2+bx+cax^2 + bx + c. We can attempt to factor it by finding two numbers that multiply to acac (the product of the coefficient of x2x^2 and the constant term) and add up to bb (the coefficient of xx).
  2. Identify Coefficients: Identify the coefficients aa, bb, and cc in the quadratic expression 2x232x+1282x^2 - 32x + 128.\newlinea=2a = 2, b=32b = -32, c=128c = 128
  3. Find Multiplying and Adding Numbers: Find two numbers that multiply to acac (2×128=2562 \times 128 = 256) and add up to bb (32-32).\newlineThe two numbers that satisfy these conditions are 16-16 and 16-16, since (16)×(16)=256(-16) \times (-16) = 256 and (16)+(16)=32(-16) + (-16) = -32.
  4. Rewrite Middle Term: Rewrite the middle term 32x-32x using the two numbers found in Step 33.\newline2x232x+128=2x216x16x+1282x^2 - 32x + 128 = 2x^2 - 16x - 16x + 128
  5. Factor by Grouping: Factor by grouping.\newlineGroup the terms into two pairs: (2x216x)(2x^2 - 16x) and (16x+128)(-16x + 128).\newlineFactor out the greatest common factor from each pair.\newline2x(x8)16(x8)2x(x - 8) - 16(x - 8)
  6. Factor out Common Binomial Factor: Factor out the common binomial factor (x8)(x - 8).\newline(2x16)(x8)(2x - 16)(x - 8)
  7. Further Factor 2x162x - 16: Recognize that 2x162x - 16 can be further factored by taking out the common factor of 22.\newline2(x8)(x8)2(x - 8)(x - 8)
  8. Write Final Factored Form: Write the final factored form.\newlineThe factored form of the expression is 2(x8)22(x - 8)^2.
