The first step in solving the equation (x+2)(x−9)=0 is to set each binomial factor equal to zero.

Here's why:

When you have a product of factors equal to zero, like (x+2)(x−9)=0, you can use the zero product property, which states that if ab=0, then either a=0, b=0, or both a and b are zero.

So, in this case: (x+2)(x−9)=0

Set each factor equal to zero:...
