Inequality
2*x^2-13*x-7 > 0

  1. an inequality in which left side of inequality greater than right side of inequality. The left side of the inequality is a sum that consists of 3 terms. The first term of the sum is a product comprising 2 factors. The first factor of the product is equal to two. The second factor of the product is a power. The base is x. The exponent is two. The second term of the sum is equal to a negative product that consists of 2 factors. The first factor of the product is thirteen. The second factor of the product is equal to x. The third term of the sum is negative seven. The right side of the inequality is equal to zero.
  2. two times x raised to the power of two plus negative thirteen multiplied by x plus negative seven greater than zero.
