Question

(2x+ 2) +(3 - 5x) 4.) (3x3 - 4x4) +(2x + 5x4)​

Answer 1

Answer:

1. $\boxed{ \bold{ \sf{ - 3x + 5}}}$

2. $\boxed{ \bold{ \sf{ {x}^{4} + 3 {x}^{3} + 2x}}}$

Step-by-step explanation:

1. $\sf{(2x + 2) + (3 - 5x)}$

When there is a ( + ) in front of expression in parentheses , the expression remains the same.

⇒$\sf{2x + 2 + 3 - 5x}$

Collect like terms

⇒$\sf{ - 3x + 2 + 3}$

Add the numbers

⇒$\sf{ - 3x + 5}$

2. $\sf{( {3x}^{3} - 4 {x}^{4} ) + (2x + 5 {x}^{4}) }$

When there is a ( + ) in front of expression in parantheses , the expression remains the same

⇒$\sf{3 {x}^{3} - 4 {x}^{4} + 2x + {5x}^{4} }$

Collect like terms

⇒$\sf{ {x}^{4} + 3 {x}^{3} + 2x}$

Hope I helped!
