Question

(19x^2+12x+12)+(7x^2+10x+13)

Answer 1

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 $26x^2+22x+25$.

Answer 2

Answer:

$\boxed{ \huge{ \boxed{ \bold{ \sf{26 {x}^{2} + 22x + 25}}}}}$

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!
