Factoring Quadratic Equations Methods

This video tutorial covers how to factor and solve quadratic equations where the leading coefficient is not 1 and not a common factor. It reviews three methods: trial and error, grouping, and bottoms up, focusing on the trial and error method. Two examples are provided to demonstrate the process of factoring and solving quadratic equations using this method, highlighting the importance of selecting the correct factors to achieve the desired middle term.

What is the main focus of the video tutorial?

• Solving linear equations

• Factoring and solving quadratic equations

• Graphing quadratic functions

• Solving cubic equations

Which method is being reviewed in detail in this video?

• Bottoms up method

• Synthetic division

• Grouping method

• Trial and error method

In the first example, what are the possible first terms for the binomial factors?

• 6X and X

• 5X and X

• 4X and X or 2X and 2X

• 3X and X

What is the correct factorization of the trinomial in the first example?

• (2X - 3)(2X + 7)

• (4X + 3)(X - 7)

• (4X - 3)(X + 7)

• (2X + 3)(2X - 7)

What are the solutions to the quadratic equation in the first example?

• X = 3/4 and X = -7

• X = 1/2 and X = -5

• X = 1/4 and X = -8

• X = 2/3 and X = -6

In the second example, what must the first terms of the binomial factors be?

• 4X and X

• 3X and X

• 5X and X

• 2X and X

Why can't a multiple of 3 be used in the second position of the binomial with 3X?

• It would make the equation unsolvable

• It would create a common factor

• It would not affect the equation

• It would result in a negative product

What is the correct factorization of the trinomial in the second example?

• (3X - 5)(X - 6)

• (3X + 6)(X + 5)

• (3X + 5)(X + 6)

• (3X - 6)(X - 5)
