Question

Add or Subtract to Simplify:
(x5 + x3) - (6x - x3 + 6x5)

Answer 1

`\boxed{ \bold{ \boxed{ \sf{ - 5 {x}^(5) + 2 {x}^(3) - 6x}}}}`

Explanation:

`\sf{( {x}^(5) + {x}^(3) ) - (6x - {x}^(3) + 6 {x}^(5)) }`

When there is a ( - ) in front of an expression in parentheses , change the sign of each term.

Also, remove the parentheses

⇒
`\sf{ {x}^(5) + {x}^(3) - 6x + {x}^(3) - 6 {x}^(5) }`

Collect like terms

⇒
`\sf{ {x}^(5) - 6 {x}^(5) + {x}^(3) + {x}^(3) - 6x}`

⇒
`\sf{ - 5 {x}^(5) + 2 {x}^(3) - 6x}`

Hope I helped!

Best regards!!
