Q. Rewrite the expression as a product of four linear factors:\newline(5x212x)22(5x212x)63 \left(5 x^{2}-12 x\right)^{2}-2\left(5 x^{2}-12 x\right)-63 \newlineAnswer:
  1. Write Given Expression: Let's first write down the given expression:\newline(5x212x)22(5x212x)63(5x^2 - 12x)^2 - 2(5x^2 - 12x) - 63\newlineWe will try to recognize this as a quadratic in form of (ax2+bx+c)(ax^2 + bx + c) where xx is replaced by (5x212x)(5x^2 - 12x).
  2. Recognize Quadratic Form: To factor the quadratic, we look for two numbers that multiply to acac (where aa is the coefficient of the squared term and cc is the constant term) and add to bb (the coefficient of the linear term). In this case, a=1a = 1, b=2b = -2, and c=63c = -63. \newlineac=1×63=63ac = 1 \times -63 = -63\newlineWe need two numbers that multiply to 63-63 and add to 2-2.
  3. Factor Quadratic: The two numbers that satisfy these conditions are 9-9 and +7+7 because 9×7=63-9 \times 7 = -63 and 9+7=2-9 + 7 = -2.\newlineNow we can rewrite the quadratic as:\newline(5x212x9)(5x212x+7)(5x^2 - 12x - 9)(5x^2 - 12x + 7)
  4. Find Two Numbers: Next, we need to factor each quadratic factor further into two linear factors. We start with the first quadratic factor:\newline5x212x95x^2 - 12x - 9\newlineWe look for two numbers that multiply to 5×9=455 \times -9 = -45 and add to 12-12.
  5. Rewrite Quadratic: The two numbers that satisfy these conditions are 15-15 and +3+3 because 15×3=45-15 \times 3 = -45 and 15+3=12-15 + 3 = -12. We can now factor the first quadratic factor as: (5x15)(x+3)(5x - 15)(x + 3)
  6. Factor First Quadratic: Now we factor the second quadratic factor:\newline5x212x+75x^2 - 12x + 7\newlineWe look for two numbers that multiply to 5×7=355 \times 7 = 35 and add to 12-12.
  7. Factor Second Quadratic: The two numbers that satisfy these conditions are 5-5 and 7-7 because 5×7=35-5 \times -7 = 35 and 57=12-5 - 7 = -12.\newlineWe can now factor the second quadratic factor as:\newline(5x7)(x1)(5x - 7)(x - 1)
  8. Combine Linear Factors: Combining all the linear factors, we get the expression as a product of four linear factors: \(5x - 1515)(x + 33)(55x - 77)(x - 11)\
