Question

Algebraic formulas of class 8


`{a}^(2) - 15b + 5b + 3ab`
Or
{a}^{2} - 15b + 5a +3ab​

Answer 1

SolutioN:-

`\sf \longrightarrow \: {a}^(2) - 15b + 5a + 3ab`

`\sf \longrightarrow \: {a}^(2) + 5a \: - 15b + 3ab`

`\sf \longrightarrow \: ({a}^(2) + 5a )\: + ( - 15b + 3ab)`

`\sf \longrightarrow \:a (a + 5 )\: + ( - 15b + 3ab)`

`\sf \longrightarrow \:a (a + 5 )\: - 3b( 5 - a)`

`\sf \longrightarrow \:a (a + 5 )\: - 3b( - a + 5)`

`\sf \longrightarrow \:a (a + 5 )\: + 3b( a - 5)`

`\sf \longrightarrow \: (a - 5 )\: (a+ 3b)`
