Q. Rewrite the expression as a product of four linear factors:\newline(x2+5x)22(x2+5x)24 \left(x^{2}+5 x\right)^{2}-2\left(x^{2}+5 x\right)-24 \newlineAnswer:
  1. Identify Expression: Let's first identify the expression we need to factor:\newlineExpression: (x2+5x)22(x2+5x)24(x^2 + 5x)^2 - 2(x^2 + 5x) - 24\newlineWe notice that this is a quadratic in form, where the variable part (x2+5x)(x^2 + 5x) is squared. Let's set a substitution to simplify the expression.\newlineLet u=x2+5xu = x^2 + 5x.\newlineNow our expression becomes:\newlineu22u24u^2 - 2u - 24
  2. Set Substitution: Next, we factor the quadratic expression u22u24u^2 - 2u - 24 as if it were a regular quadratic equation.\newlineWe look for two numbers that multiply to 24-24 and add up to 2-2. These numbers are 6-6 and +4+4.\newlineSo we can write the factored form as:\newline(u6)(u+4)(u - 6)(u + 4)
  3. Factor Quadratic Expression: Now we substitute back x2+5xx^2 + 5x for uu to get the expression in terms of xx:(x2+5x6)(x2+5x+4)(x^2 + 5x - 6)(x^2 + 5x + 4)
  4. Substitute Back to x: We now need to factor each quadratic expression further to get the linear factors.\newlineLet's start with the first quadratic expression:\newlinex2+5x6x^2 + 5x - 6\newlineWe look for two numbers that multiply to 6-6 and add up to 55. These numbers are +6+6 and 1-1.\newlineSo we can write the factored form as:\newline(x+6)(x1)(x + 6)(x - 1)
  5. Factor First Quadratic: Now let's factor the second quadratic expression:\newlinex2+5x+4x^2 + 5x + 4\newlineWe look for two numbers that multiply to 44 and add up to 55. These numbers are +4+4 and +1+1.\newlineSo we can write the factored form as:\newline(x+4)(x+1)(x + 4)(x + 1)
  6. Factor Second Quadratic: Finally, we combine all the linear factors to express the original expression as a product of four linear factors: x + \(6)(x - 11)(x + 44)(x + 11)\
