1

Factor the polynomial $80x+x^2$. Add and subtract $\left(\frac{b}{2}\right)^2$, replacing $b$ by it's value $80$

$x^2+80x+1600-1600\leq 529$

$x^2+80x+1600-1600\leq 529$

Learn how to solve inequalities problems step by step online. Solve the inequality 80x+x^2<=529. Factor the polynomial 80x+x^2. Add and subtract \left(\frac{b}{2}\right)^2, replacing b by it's value 80. Now, we can factor x^2+80x+1600 as a squared binomial of the form \left(x+\frac{b}{2}\right)^2. Calculate the square root of 1600. Moving the term -1600 to the other side of the inequation with opposite sign.

$x\leq 21.065539$

Main Topic: Inequalities

In mathematics, an inequation is a statement that an inequality holds between two values. It is usually written in the form of a pair of expressions denoting the values in question, with a relational sign between them indicating the specific inequality relation.
