Question

Simplify the sum. (4u3 + 4u2 + 2) + (6u3 – 2u + 8)

Answer 1

Answer:

$10u^{3}+4u^{2}-2u+10$ or $2(5u^{3}+2u^{2}-u+5)$

Step-by-step explanation:

we have

$(4u^{3}+4u^{2} +2)+(6u^{3}-2u+8)$

step 1

Group terms that contain the same variable

$(4u^{3}+6u^{3})+(4u^{2})+(-2u)+(2+8)$

step 2

Combine like terms

$(10u^{3})+(4u^{2})+(-2u)+(10)$

step 3

Eliminate parenthesis

$10u^{3}+4u^{2}-2u+10$

step 4

Factor the number $2$

$2(5u^{3}+2u^{2}-u+5)$

Answer 2

(4u3+4u2+2)+(6u3-2u+8)    ......remove the brackets fist

4u3+4u2+2+6u3-2u+8        ......add and subtract the like terms

10u3+4u2+2u+10
