Answer 1

Answer:

$(i) \\ (3 {x}^{2} - 2x) \div x \\ ⇒ \frac{3 {x}^{2} - 2x }{x} \\ ⇒\frac{x(3x - 2)}{x} \\ ⇒3x - 2 \\ \\ Answer: \: 3x - 2.$

$(ii) \\ (5 {a}^{3} b - 7a {b}^{3} ) \div ab \\ ⇒ \frac{5 {a}^{3} b - 7a {b}^{3} }{ab} \\ ⇒ \frac{ab(5 {a}^{2} - 7 {b}^{2}) }{ab} \\⇒ 5 {a}^{2} - 7 {b}^{2} \\ \\ Answer: \: 5 {a}^{2} - 7 {b}^{2} .$

$(iii) \\ (25 {x}^{5} - 17 {x}^{4} ) \div 5 {x}^{3} \\ ⇒ \frac{(25 {x}^{5} - 17 {x}^{4}) }{5 {x}^{3} } \\ ⇒ \frac{ {x}^{3}(25 {x}^{2} -17x) }{5 {x}^{3} } \\ ⇒ \frac{25 {x}^{2} - 17x}{5 } \\ \\ Answer: \: \frac{25 {x}^{2} - 17x }{5} .$

$(iv) \\ (4 {l}^{5} - 6 {l}^{4} + 8 {l}^{3} ) \div 2 {l}^{2} \\ ⇒ \frac{4 {l}^{5} - 6 {l}^{4} + 8 {l}^{3} }{2 {l}^{2} } \\ ⇒ \frac{2 {l}^{2} (2 {l}^{3} - 3 {l}^{2} + 4l) }{2 {l}^{2} } \\ ⇒2 {l}^{3} - 3 {l}^{2} + 4l \\ \\ Answer: \: 2 {l}^{3} - 3 {l}^{2} + 4l.$

$(v) \\ 15( {a}^{3} {b}^{2} {c}^{2} - {a}^{2} {b}^{3} {c}^{2} + {a}^{2} {b}^{2} {c}^{3} ) \div 3abc \\ ⇒ \frac{15( {a}^{3} {b}^{2} {c}^{2} - {a}^{2} {b}^{3} {c}^{2} + {a}^{2} {b}^{2} {c}^{3} ) }{3abc} \\ ⇒ \frac{15a bc( {a}^{2}bc - a {b}^{2} c + abc^{2}) }{3abc} \\ ⇒5 {a}^{2} bc - 5a {b}^{2} c + 5ab {c}^{2} \\ \\ Answer: \: 5 {a}^{2} bc - 5a {b}^{2} c + 5ab {c}^{2} .$

$(vi) \\ (3 {p}^{3} - 9 {p}^{2} q - 6p {q}^{2} ) \div ( - 3p) \\ ⇒ \frac{3 {p}^{3} - 9 {p}^{2}q - 6p {q}^{2} }{ - 3p} \\ ⇒ \frac{ - 3p(3pq - {p}^{2} + 2 {q}^{2}) }{ - 3p} \\ ⇒ 3pq - {p}^{2} + 2 {q}^{2} \\ \\ Answer: \: 3pq - {p}^{2} + 2 {q}^{2} .$

$(vii) \\ ( \frac{2}{3} {a}^{2} {b}^{2} {c}^{2} + \frac{4}{3} a {b}^{2} {c}^{2} ) \div \frac{1}{2} abc \\ ⇒ \frac{ \frac{2}{3} {a}^{2} {b}^{2} {c}^{2} + \frac{4}{3} a {b}^{2} {c}^{2} }{ \frac{1}{2} abc} \\ ⇒ \frac{abc( \frac{2}{3} abc + \frac{4}{3}bc) }{ \frac{1}{2} abc} \\ ⇒ \frac{ \frac{2}{3} abc + \frac{4}{3} bc}{ \frac{1}{2} } \\ ⇒ \frac{ \frac{2abc}{3} + \frac{4bc}{3} }{ \frac{1}{2} } \\ ⇒ \frac{ \frac{2abc + 4bc}{3} }{ \frac{1}{2} } \\ ⇒\frac{2abc + 4bc}{3} \times 2 \\ ⇒ \frac{4abc + 8bc}{3} \\ \\ Answer: \: \frac{4abc + 8bc}{3} . \: \: \: \:$
