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.
