#(49x-2)+(4x^2+x+7) = 4x^2+50x+5#

Explanation:

Regroup #(color(red)(49x) color(blue)(-2)) + (color(orange)(4x^2)color(red)(+x)color(blue)(+7))#
as
#color(white)("XXXX")##(color(orange)(4x^2))+(color(red)(49x+x))+(color(blue)(-2+7))#

#color(white)("XXXX")##=color(orange)(4x^2) + color(red)(50x) + color(blue)(5)#
