$x^2-3x\geq 0+4$
Learn how to solve problems step by step online. Solve the inequality x^2-3x+-4>=0. Moving the term -4 to the other side of the inequation with opposite sign. Add the values 0 and 4. Factor the polynomial x^2-3x. Add and subtract \left(\frac{b}{2}\right)^2, replacing b by it's value -3. Now, we can factor x^2+-3x+\frac{9}{4} as a squared binomial of the form \left(x+\frac{b}{2}\right)^2.
