First, the standard form of a quadratic equation is \[a{x^2} + bx + c = 0\hspace{0.25in}a e 0\] The only requirement here is that we have an \({x^2}\) in the equation. We guarantee that this term will be present in the equation by requiring \(a e 0\).Now, with expert-verified solutions from Algebra 2, Volume 1 1st Edition, you’ll learn how to solve your toughest homework problems.

Graphing absolute value equations. Direct variation. Systems of Equations and Inequalities. Because of that, if we are solving x² = 9, we have to allow for either correct answer. So we say, x = ± 3 and that means that x = 3 or x = -3. When we have the more complicated case of x² = 13. the square root will be x = ± √13 and that means we have two possible answers: x = +√13 and x = - √13.Exercise 20. Exercise 21. Exercise 22.
