We can rewrite the expression as a division of two fractions:
m2−13m2+2m−1÷m2−2m+12m−1 To divide fractions, we multiply by the reciprocal of the second fraction:
m2−13m2+2m−1⋅2m−1m2−2m+1 Now, we factor the polynomials:
3m2+2m−1=(3m−1)(m+1) m2−1=(m−1)(m+1) m2−2m+1=(m−1)(m−1)=(m−1)2 2m−1=2m−1 Substitute the factored expressions into the equation:
(m−1)(m+1)(3m−1)(m+1)⋅2m−1(m−1)2 Now, cancel common factors:
(m−1)(3m−1)⋅2m−1(m−1)2=(m−1)(2m−1)(3m−1)(m−1)(m−1) Cancel (m−1): 2m−1(3m−1)(m−1) Therefore, we have:
2m−1(3m−1)(m−1)
