D. -31 = 2 They are still a solutions
Let's add-5 to both sides of the equation and consider the new equation x2 + x = 6. Are 2 and --3 still
solutions?
x²+x
e.
1
Let's multiply both sides by- to get
6
= 1. Are 2 and 3 still solutions?
6
f.
Let's go back to part (d) and add 3x? to both sides of the equation and consider the new equation
x2 + x + 3x3 = 6 + 3x?. Are 2 and 3 still solutions?
