Q. Rewrite the expression as a product of four linear factors:\newline(12x2+5x)29(12x2+5x)+14 \left(12 x^{2}+5 x\right)^{2}-9\left(12 x^{2}+5 x\right)+14 \newlineAnswer:
  1. Recognize quadratic form: Recognize the given expression as a quadratic in form.\newlineThe given expression is:\newline(12x2+5x)29(12x2+5x)+14(12x^{2}+5x)^{2}-9(12x^{2}+5x)+14\newlineThis is a quadratic equation in the form of (ax+b)2c(ax+b)+d(ax+b)^{2} - c(ax+b) + d, where a=12a = 12, b=5b = 5, and c=9c = 9, d=14d = 14.
  2. Substitute variable yy: Let y=12x2+5xy = 12x^2 + 5x. We can substitute yy for 12x2+5x12x^2 + 5x to make the expression easier to work with. So the expression becomes: y29y+14y^2 - 9y + 14
  3. Factor quadratic expression: Factor the quadratic expression.\newlineWe need to factor y29y+14y^2 - 9y + 14.\newlineTo factor, we look for two numbers that multiply to 1414 and add up to 9-9.\newlineThe numbers that satisfy these conditions are 7-7 and 2-2.\newlineSo we can write the quadratic as:\newline(y7)(y2)(y - 7)(y - 2)
  4. Substitute back for yy: Substitute back 12x2+5x12x^2 + 5x for yy.\newlineNow we replace yy with 12x2+5x12x^2 + 5x in the factored form:\newline(12x2+5x7)(12x2+5x2)(12x^2 + 5x - 7)(12x^2 + 5x - 2)
  5. Factor each quadratic further: Factor each quadratic expression further.\newlineWe need to factor each quadratic expression into two linear factors.\newlineStarting with 12x2+5x712x^2 + 5x - 7, we look for two numbers that multiply to 84-84 (12×712 \times -7) and add up to 55. These numbers are 77 and 12-12.\newlineSo we can write the quadratic as:\newline(3x7)(4x+1)(3x - 7)(4x + 1)\newlineSimilarly, for 12x2+5x212x^2 + 5x - 2, we look for two numbers that multiply to 24-24 (12×212 \times -2) and add up to 55. These numbers are 84-8411 and 84-8422.\newlineSo we can write the quadratic as:\newline84-8433
  6. Combine linear factors: Combine the linear factors to express the original expression.\newlineNow we combine all the linear factors to express the original expression as a product of four linear factors:\newline(3x7)(4x+1)(3x2)(4x+1)(3x - 7)(4x + 1)(3x - 2)(4x + 1)
  7. Check for repeated factors: Check for repeated factors.\newlineWe notice that the factor (4x+1)(4x + 1) is repeated. So we can write the final expression as:\newline(3x7)(4x+1)2(3x2)(3x - 7)(4x + 1)^2(3x - 2)
  8. Verify full factorization: Verify that the expression is fully factored.\newlineWe have expressed the original expression as a product of four linear factors, including the repeated factor. There are no further factors to extract, and the expression is fully factored.
