What is the first step when factoring an algebraic expression?

• Add the terms together

• Multiply the terms together

• Find the GCF

• Remove all the variables

Factor:
10x + 15

• 100x + 150

• 10(x + 5)

• 1(10x + 15)

• 5(2x + 3)

• (x - 5)

• (x - 5x)

• (x - 5)

• x²(1 - 5)

Factor completely:

3x² + 18x +15

Hint: Factor GCF first.

• 3(x² + 6x + 5)

• (x + 5)(x + 1)

• 3(x + 5)(x + 1)

• Cannot be factored
