The first step is to move the c value to the right-hand side of the equation. This step will allow the left-hand side to eventually become a perfect square: 2x2+x=2. The next step is to make the coefficient of x2 one by dividing all terms by 2: x2+x2=1. It is necessary...
In order to solve this equation, we first need to figure out what number goes into the blank to make the left side of the equation a perfect square. (This missing number is called the constant.) By doing that, we’ll be able to factor the equation like normal. Step 2: Use the Comp...
To estimate the square root of 8 using perfect squares, we can follow these steps:1. Identify Perfect Squares: First, we need to identify the perfect squares that are close to 8. The perfect squares we consider are: - \(
