Q. Factor completely.\newline412x+9x2=4-12x+9x^{2}=
  1. Recognize the structure: Recognize the structure of the quadratic expression.\newlineThe given expression is in the form of a quadratic trinomial ax2+bx+cax^2 + bx + c.\newlineWe need to factor it into the form (dxe)(fxg)(dx - e)(fx - g), where dd, ee, ff, and gg are numbers to be determined.
  2. Identify the coefficients: Identify the coefficients of the quadratic expression.\newlineThe coefficients are a=9a = 9, b=12b = -12, and c=4c = 4.\newlineWe need to find two numbers that multiply to acac (9×4=369 \times 4 = 36) and add up to bb (12-12).
  3. Find two numbers: Find two numbers that multiply to 3636 and add up to 12-12.\newlineThe numbers 6-6 and 6-6 multiply to 3636 and add up to 12-12.
  4. Rewrite the middle term: Rewrite the middle term using the numbers found in Step 33.\newlineThe expression 412x+9x24 - 12x + 9x^2 can be rewritten as 9x26x6x+49x^2 - 6x - 6x + 4.
  5. Factor by grouping: Factor by grouping.\newlineGroup the terms to factor by grouping: (9x26x)+(6x+4)(9x^2 - 6x) + (-6x + 4).\newlineFactor out the common factors from each group: 3x(3x2)2(3x2)3x(3x - 2) - 2(3x - 2).
  6. Factor out the common binomial factor: Factor out the common binomial factor.\newlineThe common binomial factor is (3x2)(3x - 2).\newlineThe factored form is (3x2)(3x2)(3x - 2)(3x - 2) or (3x2)2(3x - 2)^2.
