Answer:
x = {3, 5}
Step-by-step explanation:
I got 3.825
your equation would be
(2x-1)(x+7)=72
when you distribute youd get
2x^2 +13x -7 =72
move the 72 over giving you
2x^2 +13x -79=0
i used the quadratic formula and the answer would be 3.825 because a negative answer wouldn’t make sense in this situation
