Answer 2

Answer:

Sum of $2x^{2} + 3x-5$ and $3x^{2} -2x + 8$  is  ($5x^{2} + x+ 3$ ) .

Step-by-step explanation:

To add : $2x^{2} + 3x-5$ and $3x^{2} -2x + 8$

Solution :

• Adding two or more terms / integers together is known as an addition. Here we have to add two algebraic expressions .
• Algebraic expression is a combination of terms by the operations such as addition , subtraction multiplication and division .
• To add given algebraic expression, we add like terms together.
• Therefore, arranging given terms in correct order, we get,

• $\left(2x^{2} + 3x -5)+\left(3x^{2} -2x + 8)$
• On removing parenthesis and adding terms we get ,  
• $\left(2x^{2} + 3x -5)+\left(3x^{2} -2x + 8)$

        $= 2x^{2} + 3x -5 +3x^{2} -2x + 8\\\\= 5x^{2} +x +3$
