1) The quotient of r and 0.2 is equal to 40.
2) r divided by 0.2 is equal to 40.
Answer:
D,0,2,-2
Step-by-step explanation:
2x^5-3x^3-20x=0
x(2x^4-3x^2-20)=0
x=0
or 2x^4-3x^2-20=0
put x²=t
2t²-3t-20=0
-20×2=-40
8-5=3
8×-5=-40
2t²-(8-5)t-20=0
2t²-8t+5t-20=0
2t(t-4)+5(t-4)=0
(t-4)(2t+5)=0
t=4
x²=4
x=2,-2
t=-5/2
x²=-5/2
it gives imaginary root. so real rational roots are 0,2,-2
by 2 integers do you mean the same numbers just one negative and one whole?
Would it be 2 because it is the smallest all those can go into and also the smallest shown
That upside down u looking thing is the " intersection " of sets a and b. That means only the numbers that are in both sets.
answer is : 2,4
