Command Solve Inequality an inequality in which left side of inequality larger than or equal to right side of inequality; the left side of the inequality is equal to a sum comprising 4 terms; the 1st term of the sum is a negative power; the base is x; the exponent is three; the 2nd term of the sum is equal to a product that contains 2 factors; the 1st factor of the product is four; the 2nd factor of the product is a power; the base is x; the exponent is two; the 3rd term of the sum is equal to a product consisting of 2 factors; the 1st factor of the product is equal to fifteen; the 2nd factor of the product is x; the 4th term of the sum is equal to negative eighteen; the right side of the inequality is equal to zero; negative x exponentiated by three plus four times x exponentiated by two plus fifteen multiplied by x plus negative eighteen larger or equal than zero. Variable Result Exact an inequality in which left side of inequality smaller than or equal to right side of inequality; the left side of the inequality is x; the right side of the inequality is equal to negative three new line an inequality in which left side of inequality greater than or equal to right side of inequality; the left side of the inequality is x; the right side of the inequality is equal to one new line an inequality in which left side of inequality less than or equal to right side of inequality; the left side of the inequality is equal to x; the right side of the inequality is equal to six; left parenthesis open brace x less or equal than negative three close brace new line open bracket x larger or equal than one new line x less or equal than six close bracket right parenthesis.
