$(x^6+x+9)+(7x^6+5)$ $=8x^6+x+14$

$(x^6+x+9)+(7x^6+5)$

$=(x^6+x+9)+1(7x^6+5)rarr$ Multiply $7x^6+5$ by 1 and

remove brackets.

$=x^6+x+9+7x^6+5rarr$ Now arrange the expression in

increasing order of exponent

$=1x^6+7x^6+x+9+5rarr$ Simplify like terms.

$=8x^6+x+14$

How do you find the sum of (x^6+x+9)+(7x^6+5)(x^6+x+9)+(7x^6+5)?
