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

ziro4ka [17]

Answer:

$\boxed{ \bold{ \boxed{ \sf{ - 5 {x}^{5} + 2 {x}^{3} - 6x}}}}$

Step-by-step 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!!
