Q. Factor the following expression completely.\newlinex416x2x3+16x2x2+32 x^{4}-16 x^{2}-x^{3}+16 x-2 x^{2}+32 \newlineAnswer:
  1. Rearrange and Combine Terms: First, let's rearrange the terms of the expression in descending order of the powers of xx.x4x316x22x2+16x+32x^4 - x^3 - 16x^2 - 2x^2 + 16x + 32Combine like terms.x4x318x2+16x+32x^4 - x^3 - 18x^2 + 16x + 32
  2. Look for Common Factors: Now, let's look for common factors in groups of terms.\newlineGroup the terms as follows: (x4x3)+(18x2+16x)+32(x^4 - x^3) + (-18x^2 + 16x) + 32\newlineFactor out the common factor x3x^3 from the first group and 2x2x from the second group.\newlinex3(x1)2x(9x8)+32x^3(x - 1) - 2x(9x - 8) + 32
  3. Factor by Grouping: We notice that there is no common factor that we can factor out from all terms, but we can look for a pattern or try to factor by grouping.\newlineLet's try to factor by grouping by rearranging the terms again:\newlinex4x3x^4 - x^3 - 18x216x18x^2 - 16x + 3232\newlineFactor out x3x^3 from the first group and 2x2x from the second group.\newlinex3(x1)x^3(x - 1) - 2x(9x8)2x(9x - 8) + 3232
  4. Factor by Grouping in Pairs: Now, we look for a common binomial factor between the groups.\newlineWe can see that there is no common binomial factor, which means we need to try a different approach.\newlineLet's try to factor by grouping in pairs:\newlinex416x2x^4 - 16x^2 - x316xx^3 - 16x - 2x2322x^2 - 32\newlineFactor out x2x^2 from the first pair and xx from the second pair.\newlinex2(x216)x(x216)2(x216)x^2(x^2 - 16) - x(x^2 - 16) - 2(x^2 - 16)
  5. Identify Common Factor: Now we can see that (x216)(x^2 - 16) is a common factor.\newlineFactor out (x216)(x^2 - 16) from each group.\newline(x216)(x2x2)(x^2 - 16)(x^2 - x - 2)
  6. Factor Difference of Squares: The expression x216x^2 - 16 is a difference of squares and can be factored further.\newlineFactor x216x^2 - 16 into (x+4)(x4)(x + 4)(x - 4).\newline(x+4)(x4)(x2x2)(x + 4)(x - 4)(x^2 - x - 2)
  7. Factor Quadratic: The quadratic x2x2x^2 - x - 2 can be factored into two binomials.\newlineFactor x2x2x^2 - x - 2 into (x2)(x+1)(x - 2)(x + 1).\newline(x+4)(x4)(x2)(x+1)(x + 4)(x - 4)(x - 2)(x + 1)
