Question

In the form (x+4)(x-2)=1, the zero-factor property can or cannot be used to solve equation?

Answer 1

The zero-factor property is

`(x+a)(x+b)=0`

Then we equate each factor by 0 and find the values of x

The given equation is

`(x+4)(x-2)=1`

Since the right side is not equal to 0, then

We can not use the zero-factor property to solve the equation

The answer is

zero-factor property cannot be used
