Answer: Hello mate!
We have the equation 2x^2 + x = 14
let's solve it for x:
2x^2 + x - 14 = 0
the solutions can be obtained with the equation:
then the solutions are:
(-1 - 10.63)/4 = -2.907, that rounded to the hundreths is equal to -2.91 (because the number after the hundredth place is a 7, so we round up)
and
(-1 +10.63)/4 = 2.407, that when rounded to the hundreths place is equal to 2.41 (the same reason as before)
then the answers are -2.91 and 2.41
