Question

M²+ 2m, m² - 4 and m²+3m +2​

Answer 1

i assume this is factorization. Hence the following:

Explanation:

1st expression = m²+ 2m

= m(m + 2)

2nd expression = m² - 4

= m² - 2²

= (m + 2)(m - 2)

3rd expression = m² + 3m + 2

= m² + (2 + 1 )m + 2

= m² + 2m + m + 2

= m(m + 2) + 1(m + 2)

= (m + 2)(m + 1)

Hence, H.C.F = (m + 2)

L.C.M = m(m + 2)(m - 2)(m + 1)
