Hey there!
Always get the variable by itself first.
4+∛2y=6
Subtract 4 on both sides.
∛2y= 2
Cube both sides.
2y= 8
Divide both sides by 2.
y=4
I hope this helps!

I cannot draw a graph so im going to explain
on the bottom u write per month and on the side and then increase the amount of money by 20$.
First of all Horner
First we try with -3
1. 2. -5. -6.
-3. 3. 6
1. -1. -2. 0
To verify: -3^3+2*-3^2+15-6=0
Now we have this equation
(X+3)*(x^2 - x -2)=0
I dont know If you know sum and product but that is the easiest way so sum= 1 product = 2 so 2 and -1 are the answers.
You can do this too by this way : b^2-4ac= D
X= (-b(+or-)d^1/2)/2a
So all the zeros
2, -1 and -3
If you want more explanation, send me a comment x
