Use the zero product property to find the solutions to the equation 2x^2+ x-1 = 2. Ox x= -1/2 or x = 2
O x=-2 or x= 1/2
O x = -3/2 or x = 1
O x = 1 or x =3/2

Which one is the correct answer, and why?

The architect's side view drawing of a saltbox-style house shows a post that supports the roof ridge. the support post is 8 ft tall. the distance from the front of the house to the support post is less than the distance from the post to the back of the house. how far from the front of the house is the support post positioned?

Problem number 26 of the rhind papyrus says: find a quantity such that when it is added to of itself the result is a 15. the modern day equation that models this problem is x + x = 15. what is the solution to the equation? x = 10 x = 12 x = 15 x = 30
