Factoring a trinomial twice first with the GCF

The video tutorial covers the process of factoring expressions, starting with identifying common factors. The instructor demonstrates factoring out a common factor of 9Y squared and then rewriting the expression as two binomials. The tutorial emphasizes understanding the relationship between the factors and the original expression, using a visual box method for clarity.

What is the first step in factoring an expression?

• Identify the greatest common factor

• Multiply all terms

• Add all coefficients

• Divide by the smallest coefficient

Which method can be used to visually represent the factoring process?

• Box method

• Triangle method

• Line method

• Circle method

After factoring out 9Y squared, what expression is left?

• Y squared plus 6Y minus 5

• Y squared plus 5Y minus 6

• Y squared minus 6Y plus 5

• Y squared minus 5Y plus 6

What two numbers multiply to 5 and add to -6?

• -5 and -1

• 5 and 1

• 3 and 2

• -3 and -2

How can the expression Y squared minus 6Y plus 5 be rewritten?

• (Y + 3)(Y + 2)

• (Y - 5)(Y - 1)

• (Y - 3)(Y - 2)

• (Y + 5)(Y + 1)
