![]() Then you need to square it, (because a2) which becomes 52/22. To figure out the a, you need to take the 5 and divide it by 2 (because 2ax), which becomes 5/2. To factor the equation, you need to first follow this equation: x 2 + 2ax + a2. which factorises into (x 3) (x + 2), a 2 3a. Think of two numbers that add to make b and multiply to make c Step 2. You may need a quick look at factorising again to remind yourself how to factorise expressions such as: x2 x 6. Solving Quadratic Equations by Factoring: Example 1 Step 1. It is based on a right triangle, and states the relationship among the lengths of the sides as \(a^2+b^2=c^2\), where \(a\) and \(b\) refer to the legs of a right triangle adjacent to the \(90°\) angle, and \(c\) refers to the hypotenuse. The 25/4 and 7 is the result of completing the square method. Quadratic equations can have two different solutions or roots. ![]() One of the most famous formulas in mathematics is the Pythagorean Theorem.
