Q. Factor the following expression completely.\newlinex416x2+3x348x+2x232 x^{4}-16 x^{2}+3 x^{3}-48 x+2 x^{2}-32 \newlineAnswer:
  1. Rearrange terms in descending order: First, we should rearrange the terms in descending order of the powers of xx to make it easier to factor.x4+3x316x2+2x248x32x^4 + 3x^3 - 16x^2 + 2x^2 - 48x - 32Combine like terms.x4+3x314x248x32x^4 + 3x^3 - 14x^2 - 48x - 32
  2. Combine like terms: Next, we look for common factors in groups of terms. We can group the first three terms and the last three terms separately. x4+3x314x2x^4 + 3x^3 - 14x^2 - 48x+3248x + 32
  3. Group terms and find common factors: Now, factor by grouping. x2(x2+3x14)16(3x+2)x^2(x^2 + 3x - 14) - 16(3x + 2)
  4. Factor by grouping: We can factor the quadratic x2+3x14x^2 + 3x - 14. \newlinex2(x2)(x+7)16(3x+2)x^2(x - 2)(x + 7) - 16(3x + 2)
  5. Factor quadratic expression: Now, we look for any common factors that can be factored out further, but there are none. So, the expression is completely factored.
