2b^2 - 2b
2b(b - 1) is your answer
hope this helps
Negative leading coefficient. Therefore it is the downward paeabola.
Discriminant of -40 therefore the parabola does not touch x-axis
so the answer is 1.
x=2
y=6
x and yt are different variables
Stacy's present age = x
Laura's present age = 8 + x
Laura's age next year = (8 + x) + 1
Also, Laura's age next year = 3x
Therefore,
3x = (8 + x) + 1
3x = 9 + x
3x - x = 9
2x = 9
x = 9/2
x = 4.5
Laura's present age = 8 + x = 8 + 4.5 = 12.5
The answer is -4 and 4, since if you multiply the two, you get the product “-16” and if you add the squares of the two, you would get 32. The other options would be +or- 16 and 1, or 8 and 2, but adding the squares of those would result in a number larger than 32, therefore, the answers are 4 and -4.
Answer: 4 and -4
