2)0
3)8
4)-6
Help me out guys.
Answer:
8
Step-by-step explanation:
The condition for the discriminant b² - 4ac is
If b² - 4ac > 0 then roots are real, irrational and unequal
If b² - 4ac > 0 and a perfect square, roots are real, rational and unequal.
Thus
b² - 4ac = 8
Answer:
3) 8
Step-by-step explanation:
Real and unequal:
B² - 4AC > 0
Irrational: B²-4AC not a perfect square
The unit rate of hours is 2 per day.
There are 7 days in a week. You studied for 14 hours total. 14/7 is 2. So, 2hr/day.
III. x + 2
Answer:
Both
Step-by-step explanation:
First,let's resolve the expression into factors
x^3-x^2-6x
x(x^2-x-6)
x(x^2-3x+2x-6)
x(x(x-3)+2(x-3))
x(×+2)(x-3)
Therefore,both of them are the factors of the expression
