Simplify the sum. (7u3 + 8u2 + 7) + (8u3 – 3u + 7)
= (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:
\(15u^3+8u^2 -3u+14\)
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, \(15u^3+8u^2 -3u+14\)
