Q. When factored completely, m5+m3−6m is equivalent to(1) (m+3)(m−2)(2) (m3+3m)(m2−2)(3) m(m4+m2−6)(4) m(m2+3)(m2−2)
Identify Common Factor: We are given the expression m5+m3−6m, and we need to factor it completely. The first step is to look for a common factor in all terms.
Factor Out 'm': We can see that each term has an 'm' in it, so we can factor out an 'm' from the entire expression.m5+m3−6m=m(m4+m2−6)
Factor Quadratic-like Expression: Now we need to factor the quadratic-like expression m4+m2−6. This is similar to factoring a quadratic equation, except that m2 is taking the place of a typical 'x' in a quadratic.
Find Multiplying Numbers: We look for two numbers that multiply to −6 and add to 1 (the coefficient of m2). These numbers are 3 and −2.
Factor Quadratic Expression: We can now factor the expression m4+m2−6 as (m2+3)(m2−2). m(m4+m2−6)=m(m2+3)(m2−2)
Final Factored Form: We have factored the expression completely, and the factored form is m(m2+3)(m2−2).
