5x^3 -3x^2 +8x +10 Just combine all the like terms and multiply everything in the second parentheses by -1
The mixed number of 31/6 is 5 1/6
Hope it helps!
Answer:
- x = 0 or 1
- x = ±i/4
- x = -5 (twice)
Step-by-step explanation:
Factoring is aided by having the equations in standard form. The first step in each case is to put the equations in that form. The zero product property tells you that a product is zero when a factor is zero. The solutions are the values of x that make the factors zero.
1. x^2 -x = 0
x(x -1) = 0 . . . . . x = 0 or 1
__
2. 16x^2 +1 = 0
This is the "difference of squares" ...
(4x)^2 - (i)^2 = 0
(4x -i)(4x +i) = 0 . . . . . x = -i/4 or i/4 (zeros are complex)
__
3. x^2 +10x +25 = 0
(x +5)(x +5) = 0 . . . . . x = -5 with multiplicity 2
Answer:
3 points
Step-by-step explanation:
(-3,2),(-3,3)
(1,4),(1,-4)
(2,-2),(2,-4)
we have to remove three points to make it a function.
I think it is 7. hope this helps
