Find the sum and express it in simplest form.
(-t^2 - 6t - 3) + (-4t^2 + 2t - 4)

-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.

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
