Question

7a²b + 5ab² - 4ab² - 3ab² + 2a²b²
can you give me the steps and explaination ​

Answer 1

Given :-

`\begin{gathered}\\ \large\dashrightarrow\mathsf {7a²b+5ab²-4ab²-3ab²+2a²b²} \\ \end{gathered}`

Combine like terms :-

`\begin{gathered}\\ \large\dashrightarrow\mathsf {5ab²-4ab²-3ab²+7a²b+2a²b²} \\ \end{gathered}`

`\begin{gathered}\\ \large\dashrightarrow\mathsf {(5-4-3)ab²+7a²b+2a²b²} \\ \end{gathered}`

`\begin{gathered}\\ \large\dashrightarrow\mathsf {-2ab²+7a²b+2a²b²} \\ \end{gathered}`

Two factorisation ways :-

★ 7a²b-2ab²(1+a)

___________Or___________

★ ab(7a-2b+2ab)

Answer 2

• 7a²b+5ab²-4ab²-3ab²+2a²b²

Combine like terms

• 5ab²-4ab²-3ab²+7a²b+2a²b²
• (5-4-3)ab²+7a²b+2a²b²
• -2ab²+7a²b+2a²b²

Two factorisation ways

• 7a²b-2ab²(1+a)

Or

• ab(7a-2b+2ab)
