Question

Subtract.(6t² - 5t) - (2t² - 9t + 6)

Answer 1

We are given the following equation:

`\mleft(6t^(2)-5t\mright)-(2t^(2)-9t+6​)`

Now we use the distributive property for the parenthesis:

`6t^(2)-5t-2t^(2)+9t-6​`

Now we associate like terms, that is, terms that have the same variable elevated to the same exponent:

`(6t^2-2t^2)+(-5t+9t)-6`

Now we add like terms:

`4t^2+4t-6`

Since this expression can't be simplified any further then this is the final answer.
