Solve for x:
x^3 + x^2 + 4 x + 4 = 0
The left hand side factors into a product with two terms:
(x + 1) (x^2 + 4) = 0
Split into two equations:
x + 1 = 0 or x^2 + 4 = 0
Subtract 1 from both sides:
x = -1 or x^2 + 4 = 0
Subtract 4 from both sides:
x = -1 or x^2 = -4
Take the square root of both sides:
Answer: x = -1 or x = 2 i or x = -2 i

Answer:
The coefficient of the leading term is -1/16.
Step-by-step explanation:
G(x)=-1/6x^4-3x+5 has already been written in "standard form," that is, by descending powers of x. The coefficient of the leading term is -1/16; that's the coefficient of the highest power of x.
