Find the sum and express it in simplest form.

(-t^2 - 6t - 3) + (-4t^2 + 2t - 4)

it is - 5t^2 - 4t - 7 to the mf test

Answer: - 5t^2 - 4t - 7

Step-by-step explanation:

(-t^2 - 6t - 3) + (-4t^2 + 2t - 4)

To find the sum, we need to open the brackets

Note: the signs are very important to be taken notice of

Hint : - * - = +

- * + = -

+ * + = +

= - t^2 - 6t - 3 - 4t^2 + 2t - 4

Collecting the like terms

= - t^2 - 4t^2 - 6t + 2t - 3 - 4

= - 5t^2 - 4t - 7

We can't get more futher, unless we want to find the values of t using completing the square method or through algebra equation.
