Abū Kāmil Shujā ibn Aslam (Egypt, 10th century) in particular was the first to accept irrational numbers (often in the form of a square root, cube root or fourth root) as solutions to quadratic equations or as coefficients in an equation. The 9th century Indian mathematician Sridhara wrote down rules for solving quadratic equations.

If we are unsure how to rewrite quadratic equations so we can solve it using factoring method, we can use the formula for quadratic equation: We write x 1,2 because it represents 2 solutions of the equation. Here is a practice question : We see that a is 3, b is -10 and c is 3. We use these numbers in the equation and do some calculations. Homework and Practice 10-1 Solving Two-Step Equations LESSON Write and solve a two-step equation to answer the following questions. 1. Sue wants to buy a new printer that costs $189.
