Q. Factor completely:\newline4k4+43k2v611v12 4 k^{4}+43 k^{2} v^{6}-11 v^{12} \newlineAnswer:
  1. Identify Type and Factors: Identify the type of polynomial and look for common factors.\newlineThe given polynomial is a quadratic in form with respect to k2k^2, where k2k^2 is the variable and v6v^6 is treated as a constant. There are no common factors for all terms.
  2. Set Up Quadratic Form: Set up the polynomial as a quadratic in terms of k2k^2. Let's rewrite the polynomial by substituting k2k^2 with a new variable, say mm. So the polynomial becomes: 4m2+43m11v64m^2 + 43m - 11v^6, where m=k2m = k^2.
  3. Factor the Quadratic: Factor the quadratic polynomial.\newlineWe need to find two numbers that multiply to (4)(11v6)=44v6(4)(-11v^6) = -44v^6 and add up to 4343. These numbers are 4444 and 1-1.\newlineRewrite the middle term using these two numbers:\newline4m2+44mm11v64m^2 + 44m - m - 11v^6\newlineGroup the terms to factor by grouping:\newline(4m2+44m)(m+11v6)(4m^2 + 44m) - (m + 11v^6)\newlineFactor out the common factors in each group:\newline4m(m+11)v6(m+11)4m(m + 11) - v^6(m + 11)\newlineNow factor out the common binomial factor (m+11)(m + 11):\newline(m+11)(4mv6)(m + 11)(4m - v^6)
  4. Substitute Back: Substitute back k2k^2 for mm.\newlineReplace mm with k2k^2 in the factored form:\newline(k2+11)(4k2v6)(k^2 + 11)(4k^2 - v^6)
  5. Check Factored Form: Check the factored form by expanding it to ensure it matches the original polynomial.\newlineExpanding (k2+11)(4k2v6)(k^2 + 11)(4k^2 - v^6) gives:\newline4k4k2v6+44k211v64k^4 - k^2v^6 + 44k^2 - 11v^6\newlineCombine like terms:\newline4k4+(44k2k2v6)11v64k^4 + (44k^2 - k^2v^6) - 11v^6\newlineSince 44k2k2v644k^2 - k^2v^6 does not simplify to 43k2v643k^2v^6, we have made a mistake.
