Step-by-step explanation:
Hello,
We need to use the <u>distributive property</u> which means that for a, b and c real numbers a(b+c)=ab+ac
So here we can write
![x(x+1)=72\\ x*x+x*1=72\\ x^2 + x -72 = 0\\](https://tex.z-dn.net/?f=x%28x%2B1%29%3D72%5C%5C%3C%3D%3E%20x%2Ax%2Bx%2A1%3D72%5C%5C%3C%3D%3E%20x%5E2%20%2B%20x%20-72%20%3D%200%5C%5C)
