$x^2+20x=200$
Learn how to solve one-variable linear equations problems step by step online. Solve the equation x(x+20)=200. Solve the product x\left(x+20\right). Factor the polynomial x^2+20x. Add and subtract \left(\frac{b}{2}\right)^2, replacing b by it's value 20. Now, we can factor x^2+20x+100 as a squared binomial of the form \left(x+\frac{b}{2}\right)^2. The square root of 100 is .
