partial fraction decomposition of a sum consisting of 3 terms; (6*x^3+4*x+1)/(x^4+x^2) | investigate the way to multiply out a sum that contains 7 terms. (4*x^3+2*x-3)*(2*x^4+3*x^2-5)

Command

Solve

Inequality
abs(2+4*x) >= 6

  1. 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 absolute value of a sum that consists of 2 terms. The 1st term of the sum is two. The 2nd term of the sum is equal to a product consisting of 2 factors. The 1st factor of the product is four. The 2nd factor of the product is equal to x. The right side of the inequality is equal to six.
  2. absolute value of two plus four multiplied by x larger or equal than six;
Variable
Result
A nonpolynomial inequality has been used, so the solution set may be incorrect.

Exact

<<x = 1>> or <<x = -2>> or <<x < -2>> or <<1 < x>>

  1. an inequality in which left side of inequality less than right side of inequality. The left side of the inequality is equal to one. The right side of the inequality is equal to x.
  2. open parenthesis one smaller than x close parenthesis;
