Sagot :

Answer

The coefficient of x³ is -1.

Explanation

When a variable has no coefficients, it is assumed to have a coefficient of 1 in math concepts. If the equation includes this coefficient, you don't need to input 1.

The solution becomes -1 due to the minus sign preceding the equation, which indicates that the coefficient is a negative integer.
