Zero product says that if you have
x=0, then the non-zero factors equal zero
so
try to move all to one side to get it to equal zero and factor
4y^3-4=y-16y^2
add 16y^2 to both sides
4y^3+16y^2-4=y
subtract y
4y^3+16y^2-y-4=0
gropu and factor
(4y^3+16y^2)+(-y-4)=0
(4y^2)(y+4)+(-1)(y+4)=0
reverse distribute
ba+ca=a(b+c)
(4y^2-1)(y+4)=0
set each to zero
4y^2-1=0
add 1
4y^2=1
divide by 4
y^2=1/4
square root both sides
y=+/-1/2
y+4=0
minus 4
y=-4
y=-4,-1/2,1/2
answer is A -4,-1/2,1/2

➷ r = k/v^2
Substitute the values in:
120 = k/1^2
Multiply both sides by 1^2 to find k
k = 120
Substitute new values in:
r = 120/10^2
Solve:
r = 1.2
