Answer:
Step-by-step explanation:
X Y
--------
1 0.50
2 0.25
3 0.13
4 0.06
5 0.03
To solve this equation simply find 2 numbers that multiply to give -4 and add also to give 3, these numbers are 4 and -1. Since 4 • -1 = -4 and 4 + -1 = 3.
X^2 + 3x - 4 = 0
(X - 1)(X + 4) = 0
X = -4 and X = 1 in ascending order.
675
15*45
3*5 5*9
3*3
3^3*5^2=675
