Solve for x, where x>0 and 0=-9x^2-3x+2 Express your answer as a simplified common fraction.
Multiply through by - 1 and we have
9x^2 + 3x - 2 = 0
(3x + 2) (3x - 1) = 0
Only the second factor produces a positive solution of 1/3
2.
For how many positive integers x is x^2+4x+4 between 10 and 50?
Note x^2 + 4x + 4 = (x + 2)^2
Whe x = 1 (x + 2)^2 = 9
When x = 2 (x + 2)^2 = 16
When x = 5 (x + 2)^2 = 49
When x = 6 (x + 2)^2 = 64
So.... four integers....2, 3 , 4 , 5
