-The equation is actually
5x^2 -2x+1=0;
-The discriminant is b^2 -4ac=4-4•5•1=4-20=-16
-this means that the equation has no real number solutions
Answer:
Step-by-step explanation:
350=12(x+20)
(divide both sides by 12)
29.1667=x+20
(subtract 20 from both sides)
x=9.16667
X (9.17) is the additional amount of money the student must save each month in order to reach his goal.

Answer:
x=-1
y=15
Step-by-step explanation:
This works because completing the square is essentially demonstrating what g(x) - where g(x) in this case = x^2 - would have to be translated by to give the function you have.
So by completing the square you have shown that the function you've been given has been shifted to the left by -1, stretched by a factor of 2 along the y axis and shifted up by 15.
