Factoring Quadratic Equations Challenges

The video tutorial explains the concept of the inverted triangle function, defined as x plus one over x, for non-zero integers x. The goal is to find possible integer values of t for which the function equals t. The instructor demonstrates how to rearrange the equation to solve for x in terms of t, leading to a quadratic equation. By exploring different values of t, the instructor identifies that t equals negative two allows for integer solutions, specifically x equals negative one. The video concludes with a verification of the solution and a discussion of why other values of t do not work.

What is the definition of the inverted triangle function?

• x minus one over x

• x plus one over x

• x divided by one over x

• x times one over x

What is the first step in solving the equation for x as a function of t?

• Subtract x from both sides

• Divide both sides by x

• Multiply both sides by x

• Add x to both sides

What type of equation do we get after rearranging the original equation?
