Answer:
(x-2), (x+2), (3x-5)
Step-by-step explanation:
Factors of 3: ±1, ±3
Factors of 20: ±1, ±2, ±4, ±5, ±10, ±20
Possible factors of the polynomial: ±1, ±2, ±3, ±4, ±5, ±10, ±20, .... (there's a lot more but you probably do not need to list them all)
Pick a number to divide the polynomial by (I picked 2)
(3x³-5x²-12x+20)÷(x-2) = 3x²+x-10
So (x-2) is a factor of f(x) = 3x³-5x²-12x+20
Factor 3x²+x-10 = (3x-5)(x-2) these are the other factors of f(x) = 3x³-5x²-12x+20
The slope-point form:
We have two points (4, 5) and (-3, -1). Substitute:
For point (4, 5):
For point (-3, -1):

Answer:
30 9/20
Step-by-step explanation:
(50 3/4)-((2/5) x (50 3/4)
=30.45
=30.45/1
=30.45/1 x 100/100
=3045/100
=3045÷5/100÷5
=30 9/20
30.45= 30 9/20
Hope this helps have a good day.
