Completing the Square - Part 2

This video tutorial covers solving quadratic equations using the method of completing the square. It begins with an introduction to the concept, followed by a detailed example problem. Viewers are then given a practice problem to solve independently. The video concludes with a summary and a preview of the next topic, which involves plotting quadratics using the same method.

What are the two methods mentioned for solving quadratics?

• Completing the square and using the quadratic formula

• Graphing and using the quadratic formula

• Factoring and graphing

• Using the quadratic formula and substitution

What is the first step in completing the square for the equation x^2 + 14x?

• Subtract 49 from both sides

• Find half of 14 and square it

• Add 19 to both sides

• Divide by 2

After completing the square, what is the next step to solve the equation?

• Add 7 to both sides

• Subtract 7 from both sides

• Square both sides

• Multiply both sides by 2

What should you do if a quadratic equation has a factor like 3?

• Ignore the factor and solve normally

• Factor it out and solve normally

• Multiply it by 2

• Add it to both sides

What additional information does completing the square provide when plotting quadratics?

• The roots of the equation

• The vertex of the parabola

• The axis of symmetry

• The y-intercept
