1)19 + (-8h + h)
2) 2w(8w =15)
only simplify is needed (impossible to solve anyways)
thnx!

Question 1
19 - 7h
Question 2
2 w ( 8 w - 15 )
16 w ² - 30 w

1) 19+ (-8h + h) = 19 - 7h
2) 2w(8w) = 15 ( I think there is a mistake in your writing)
16w^2 = 15
w^2 = 15/16
w = + squareroot(15) /4 or w = -squareroot (15) /4

1. 19 -8h + h = 19 - 7h
2. 16W^2 = 30W
8W^2 - 15W = 0
