Simplify (2x^2 + x + 4)+(-3+7x + 8x^2)
i know how to im just lazy

10 x^2 + 8 x + 1

Step-by-step explanation:

Simplify the following:

8 x^2 + 2 x^2 + 7 x + x - 3 + 4

Grouping like terms, 8 x^2 + 2 x^2 + 7 x + x - 3 + 4 = (2 x^2 + 8 x^2) + (x + 7 x) + (4 - 3):

(2 x^2 + 8 x^2) + (x + 7 x) + (4 - 3)

2 x^2 + 8 x^2 = 10 x^2:

10 x^2 + (x + 7 x) + (4 - 3)

x + 7 x = 8 x:

10 x^2 + 8 x + (4 - 3)

4 - 3 = 1:

10 x^2 + 8 x + 1
