Question

simplify the following
(w ² + 3w+ 4) + (3w² - 5w + 1)​

Answer 1

Answer:

16w

Step-by-step explanation:

w²(3w²-5w+1)+3w(3w²-5w+1)+4(3w²-5w+1)

3w⁴-5w³+w²+3w³-15w²+3w+12w²-20w+4

3w.w³-5(1)+w²+3(1)-15w²+3w+12w²-20w+4

3w(1)-5-2w²+3+3w-20w+4

3w-2w²-17w+2

-2w²-14w+2

-2(w²-7w+1)

we know 1+w+w²=0=====> 1+w²=-w

-2(-w-7w)

-2(-8w)

16w
