How to find the roots of a quadratic polynomial

This video covers the concept of quadratic zeros, methods to find them, and their applications in real life.

What is the first step in finding the zeros of a quadratic polynomial?

• Divide both sides by a variable

• Add a constant to both sides

• Multiply both sides by a constant

• Set the equation equal to zero

Which method is suggested for factoring a quadratic equation?

• The box method

What are the two numbers that multiply to -18 and add to -7 in the given example?

• -2 and 9

• -3 and 6

• -6 and 3

• -9 and 2

What is the factored form of the quadratic equation in the example?

• (X + 2)(X + 9)

• (X - 2)(X - 9)

• (X - 9)(X + 2)

• (X + 9)(X - 2)
