Factoring a trinomial when a is a negative 1

The video tutorial explains how to factor out negatives from an expression, making it easier to evaluate. It demonstrates finding factors of 54 and determining which should be negative to achieve a positive sum. The lesson concludes with a brief mention of future topics.

What is the recommended method to simplify an expression with a negative sign in front?

• Add a positive sign to the expression

• Ignore the negative sign

• Factor out the negative sign

• Multiply the expression by zero

When factoring a quadratic expression, what should you do if you can't identify the factors easily?

• Guess the factors

• List all possible factors of the constant term

• Skip the problem

• Use a calculator

If two numbers multiply to a negative product, what must be true about one of the numbers?

• Both numbers must be positive

• Neither number can be negative

• One number must be negative

• Both numbers must be negative

In a quadratic expression where the product is negative and the sum is positive, which number should be negative?

• The larger number

• The smaller number

• Neither number

• Both numbers

What is the final step after determining the correct factors in a quadratic expression?

• Add the factors together

• Multiply the factors

• Divide the factors

• Rewrite the expression in factored form
