Practice writing and solving quadratic equations.
liberstina [14]

Answer:

\boxed{\sf \ \ \ x^2 + x -72 = 0 \ \ \ }

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\\
