Question #dfd45

Answer 1

`chi =-4` and `chi=3` are solutions to this equation.

Explanation:

This question tests our understanding of how to create a result of zero using multiplication. The left hand side of the equation is basically two things multiplied with each other:

`color{red}((chi-3)) color{blue}((chi+4))=0`

We know that when you multiply two numbers together, the only way to get a result of zero is for one or both of the numbers to be zero to begin with. That implies that either factor being zero will satisfy the equation.

`color{red}(chi-3) = 0`
`=> chi=3`

or

`color{blue}(chi+4) = 0`
`=> chi=-4`

Therefore

`chi=-4` and `chi=3` are solutions to this equation.
