x = -1
x = 3
Step-by-step explanation:

Add 1 to both sides:

Factor the left side:

Square root both sides:

Therefore:


You have to square the binomial.
(x^3 + 4y) (x^3 + 4y)
Using FOIL:
x^9 + 4(x^3)y + 4(x^3)y + 16y^2
x^9 + 8(x^3)y + 16y^2
You could also use the formula: (a+b)^2 = (a^2 + 2ab + b^2).
