Question

Simplify (7g2 + 9g + 5) + (7g2 – 18g – 10)
Answer
14g2 + 9g – 5
14g2 – 9g – 5
14g2 – 9g + 5
14g2 + 9g + 5

Answer 1

in this case we can take off bracket
so we have

7g2 + 9g + 5 + 7g2 – 18g – 10

sum cofficients of \[g^2\] and cofficient of g example:

\[\Large 2x^2+3x^2=(2+3)x^2=5x^2\]
in your case you have \[g^2\] try to sum them...
