Identify Type and Factors: Identify the type of polynomial and look for common factors.The given polynomial is a quadratic in form with respect to k2, where k2 is the variable and v6 is treated as a constant. There are no common factors for all terms.
Set Up Quadratic Form: Set up the polynomial as a quadratic in terms of k2. Let's rewrite the polynomial by substituting k2 with a new variable, say m. So the polynomial becomes: 4m2+43m−11v6, where m=k2.
Factor the Quadratic: Factor the quadratic polynomial.We need to find two numbers that multiply to (4)(−11v6)=−44v6 and add up to 43. These numbers are 44 and −1.Rewrite the middle term using these two numbers:4m2+44m−m−11v6Group the terms to factor by grouping:(4m2+44m)−(m+11v6)Factor out the common factors in each group:4m(m+11)−v6(m+11)Now factor out the common binomial factor (m+11):(m+11)(4m−v6)
Substitute Back: Substitute back k2 for m.Replace m with k2 in the factored form:(k2+11)(4k2−v6)
Check Factored Form: Check the factored form by expanding it to ensure it matches the original polynomial.Expanding (k2+11)(4k2−v6) gives:4k4−k2v6+44k2−11v6Combine like terms:4k4+(44k2−k2v6)−11v6Since 44k2−k2v6 does not simplify to 43k2v6, we have made a mistake.
