Question

Find the sum. Write your answer in standard form. Look at the screenshot below!

Answer 1

Explanation:

`\tt{(6 {x}^(3) + 3 {x}^(2) + 3) + (2 {x}^(3) - 5x + 1) }`

Remove the unnecessary parentheses

⟶
`\tt{6 {x}^(3) + 3 {x}^(2) + 3 + 2 {x}^(3) - 5x + 1 }`

Combine like terms. Like terms are those which have the same base. Remember that only coefficients of like terms can be added or subtracted and their bases remains the same.

⟶
`\tt{6 {x}^(3) + 2 {x}^(3) +3 {x}^(2) + 3 + 1 - 5x}`

⟶
`\tt{8 {x}^(3) + 3 {x}^(2) + 4 - 5x}`

In standard form , the expression should be written in a way that power of variables goes from highest to lowest.

`\red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed {\underline{ \tt{8 {x}^(3) + 3 {x}^(2) - 5x + 4}}}}}}}`

Hope I helped ! ♡

Have a wonderful day / night ! ツ
