Question

Practice writing and solving quadratic equations.

Answer 1

Answer:

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

Step-by-step explanation:

Hello,

We need to use the distributive property which means that for a, b and c real numbers a(b+c)=ab+ac

So here we can write

$x(x+1)=72\\ x*x+x*1=72\\ x^2 + x -72 = 0$

do not hesitate if you have any question
