Question

PLEASE HELP ME I NEED TO PASS THIS!!!!!!!!!!!!!!!!!!!

Answer 1

You would use distribution

The answer is 
50w^7 + 40w^4 - 20w^2

Answer 2

The first step for solving this expression is to multiply each term in the parenthesis by 10w.
10w × 5$w^{6}$ + 10w × 4w³ - 10w × 2w
Calculate the product of 10w × 5$w^{6}$ 
50$w^{7}$ + 10w × 4w³ - 10w × 2w
Calculate the product of 10w × 4w³
50$w^{7}$ + 40$w^{4}$ - 10w × 2w
Lastly,, calculate the final product of -10w × 2w
50$w^{7}$ + 40$w^{4}$ - 20w²
Since you cannot simplify any further,, the correct answer to your question will be 50$w^{7}$ + 40$w^{4}$ - 20w².
