A square piece of paper has an area of x2 square units. A rectangular strip with a width of 2 units and a length of x units is c

vlabodo [156]

Let

x--------> the length side of the original square paper

we know that

the area of the original square paper is equal to

$A1=x*x=x^{2} \ units^{2}$

the area of the remaining piece of paper is equal to

$A2=x^{2} -2x\\ A2=120\ units^{2} \\ so\\ x^{2} -2x=120\\ x^{2} -2x-120=0$

therefore

the answer is the option

x2 − 2x − 120 = 0
