1.	m3 (m – 2) + 2m2 (m + 3) – 6m (m – 4) = ……………….. A) m – 24m2 B) m2 + 24m C) m2 + 2m D) m + 4m2
Answer» Correct option is B) m² + 24m Correct option is (B) m⁴+ 24m \(m^3(m–2)+2m^2(m+3)–6m(m–4)\) \(=m^4-2m^3+2m^3+6m^2-6m^2+24m\) = \(m^4+24m\)

m3 (m – 2) + 2m2 (m + 3) – 6m (m – 4) = ……………….. A) m – 24m2 B) m2 + 24m C) m2 + 2m D) m + 4m2

Answer»

Correct option is B) m² + 24m

Correct option is (B) m⁴+ 24m

\(m^3(m–2)+2m^2(m+3)–6m(m–4)\)

\(=m^4-2m^3+2m^3+6m^2-6m^2+24m\)

= \(m^4+24m\)
