Question

Simplify the sum. (7u3 + 8u2 + 7) + (8u3 – 3u + 7)

Answer 1

= (7u³ + 8u² + 7) + (8u³ - 3u + 7)
Operate like terms together:

= 7u³ + 8u³ + 8u² - 3u + 7 + 7
= 15u³ + 8u² - 3u + 14

In short, Your Answer would be: 15u³ + 8u² - 3u + 14

Hope this helps!

Answer 2

Answer:

$15u^3+8u^2 -3u+14$

Step-by-step explanation:

Like terms are those terms which have same variable  to the same power.

Simplify:

$(7u^3+8u^2+7)+(8u^3 -3u+7)$

Remove the bracket:

$7u^3+8u^2+7+8u^3 -3u+7$

Combine like terms;

$15u^3+8u^2 -3u+14$

Therefore, the sum of $(7u^3+8u^2+7)+(8u^3 -3u+7)$ is, $15u^3+8u^2 -3u+14$
