Question

(2x+4)(x-1) express as a trinomial

Answer 1

`\huge\boxed{\bf{(2x + 4)(x - 1) = 2x^2 + 8x - 4}}`

Explanation:

`\sf \to (2x + 4)(x - 1)`

`\sf \to x(2x + 4) + 4(x - 1)`

`\sf \to 2x^2 + 4x + 4x - 4`

`\sf \to 2x^2 + 8x - 4`

`\:`

`\huge\colorbox{red}{BlackPain}`

Answer 2

`\\\\\hookrightarrow 2x^(2) +2x-4`

Explanation:

`\hookrightarrow (2x+4)(x-1) \\\\\hookrightarrow 2x(x-1)+4(x-1)\\\\\hookrightarrow 2x^(2) -2x+4x-4\\\\\hookrightarrow 2x^(2) +2x-4`
