Answer:

<h3>\boxed{ \huge{ \boxed{ \bold{ \sf{26 {x}^{2}  + 22x + 25}}}}}</h3>

Step-by-step explanation:

\sf{(19 {x}^{2}  + 12x + 12) + ( {7x}^{2}  + 10x + 13)}

Remove the unnecessary Parentheses

⇒\sf{19 {x}^{2}  + 12x + 12 + (7 {x}^{2}  + 10x + 13)}

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

⇒\sf{19 {x}^{2}  + 12x + 12 + 7 {x}^{2} + 10x + 13}

Collect like terms

⇒\sf{26 {x}^{2}  + 22x + 12 + 13}

Add the numbers

⇒\sf{26 {x}^{2}  + 22x + 25}

Hope I helped!

Best regards!

Answer:

26x^2+22x+25

Step-by-step explanation:

We remove the brackets, getting 19x^2+12x+12+7x^2+10x+13.

We then combine like terms, getting (19+7)x^2+(12+10)x+(12+13).

As a result, we get 26x^2+22x+25.
