$x^2-2x<8$
Learn how to solve inequalities problems step by step online. Solve the inequality x^2<2x+8. Grouping terms. Factor the polynomial x^2-2x. Add and subtract \left(\frac{b}{2}\right)^2, replacing b by it's value -2. Now, we can factor x^2+-2x+1 as a squared binomial of the form \left(x+\frac{b}{2}\right)^2. Moving the term -1 to the other side of the inequation with opposite sign.
