Use the zero product property to find the solutions to the equation 2x2 + x – 1 = 2.
FromTheMoon [43]

2 {x}^{2} + x - 1 = 2

Subtract sides -2

2 {x}^{2} + x - 1 - 2 = 2 - 2

2 {x}^{2} + x - 3 = 0

(x - 1)(2x + 3) = 0

_________________________________

x - 1 = 0

x = 1

##############################

2x + 3 = 0

x =  -  \frac{3}{2}  \\

There was a blizzard. Snow was falling at the rate of 4 1/2 inches per hour. If the snow keeps acclimating how long will 5 feet
Archy [21]
5 feet = 60 inches
4 1/2 inches = 1 hour
60 inches = 1 ÷ 4 1/2 x 60
= 13 1/3 hours

If the snow keeps accumulating, it would take 13 1/3 hours for 5 feet of snow to accumulate.
