Factoring When a=1 Practice

What is the standard form of a quadratic equation?

• ax^2 + bx + c

• ax + bx^2 + c

• a + bx + cx^2

• ax^2 + bx - c

Which of the following expressions has a-values of 1?

• 2x^2 + 3x - 1

• x^2 - 4x + 16

• 7x^2 - 8x - 2

• x^2 - 5x + 21

What is the first step to factor?

• Write the squared term in the top left box and write the constant in the bottom right box

• Check to see if you can factor out a GCF (Greatest Common Factor)

• Add the missing diagonal terms

• Multiply the b-value to the c-value

In the process of factoring when a=1, after checking for a GCF, where do you write the squared term?

• In the bottom right box

• In the top left box

• In the bottom left box

• In the top right box

• In the top right box

• In the bottom left box

• In the top left box

• In the bottom right box
