Factoring Quadratic Functions with Ninja X

The video tutorial covers credit factoring, focusing on factoring polynomials with three terms. It introduces the concept of factor pairs for both positive and negative numbers and demonstrates the factoring process through several examples. The tutorial emphasizes the importance of setting up equations in standard form and adjusting signs to achieve the correct factors. Advanced techniques for more complex polynomials are also discussed.

What is the first step in credit factoring?

• Applying the ninja X method

• Listing all factor pairs

• Determining if 'B^2 - 4AC' is a perfect square

• Finding the value of 'a'

How do you determine the sign of factors for a positive product?

• Either both factors are positive or both are negative

• One factor must be negative

• Both factors must be negative

• Both factors must be positive

In the example 'x^2 + 11x + 28', what are the correct factors?

• (x + 4)(x - 7)

• (x - 4)(x + 7)

• (x - 4)(x - 7)

• (x + 4)(x + 7)

What is crucial about the coefficient 'a' in quadratic factoring?

• It must be positive

• It must be negative

• It does not matter

• It must be zero

How do you handle a negative 'a' coefficient in quadratic equations?

• Ignore the negative sign

• Multiply the equation by -1

• Take the negative sign outside

• Change all terms to positive

In the example 'y^2 - 7y - 8', what are the correct factors?

• (y + 8)(y - 1)

• (y - 1)(y + 8)

• (y - 8)(y + 1)

• (y + 1)(y - 8)

When 'a' is not equal to 1, what additional step must be taken?

• Reduce the resulting fractions

• Ignore the coefficient 'a'

• Apply the ninja X method directly

• Multiply all terms by 'a'

In the example with 'a' not equal to 1, resulting in '5x^2 + 12x + 7', what are the correct factors after reduction?

• (x + 7)(x + 5)

• (x + 5)(x + 7)

• (5x + 1)(x + 7)

• (x + 1)(5x + 7)

What is the correct factorization for '7x^2 - 10x - 8'?

• (x + 4)(7x - 2)

• (7x - 4)(x + 2)

• (x - 4)(7x + 2)

• (7x + 4)(x - 2)

For the equation 'x^2 - 15x + 56', what are the correct factors?

• (x + 8)(x - 7)

• (x - 8)(x + 7)

• (x + 7)(x + 8)

• (x - 7)(x - 8)
