Question

9x(3x-8)Who can simplify it?

Answer 1

Starting with the expression:

`9x(3x-8)`

Use the distributive property to expand the parenthesis:

`=9x(3x)+9x(-8)`

Multiply the expressions in each term to eliminate both parenthesis:

`\begin{gathered} =9x\cdot3x-9x\cdot8 \\ =9\cdot3\cdot x\cdot x-9\cdot8\cdot x \\ =27x^2-72x \end{gathered}`

Therefore:

`9x(3x-8)=27x^2-72x`
