$x^2+8x>0-9$
Learn how to solve inequalities problems step by step online. Solve the inequality x^2+8x+9>0. Moving the term 9 to the other side of the inequation with opposite sign. Subtract the values 0 and -9. Factor the polynomial x^2+8x. Add and subtract \left(\frac{b}{2}\right)^2, replacing b by it's value 8. Now, we can factor x^2+8x+16 as a squared binomial of the form \left(x+\frac{b}{2}\right)^2.
