Algebra II MP4 Assessment

Which of the following represents the first step in solving:

y = x² + 3x - 5

y = x + 3

• x² - 3x + 5 = x - 3

• Set the expressions with x equal to each other.

• Add the expressions with x together and set them equal to zero.

• x² + 3x - 5 = 0

Name the parent function.

• cube root
• quadratic
• cubic
• square root

Solve by factoring.

(You have to write it out as a math equation first.)

"x squared, minus three x, minus twenty-eight equals zero."

• x = -4

• x = -2, 8

• x = -4, 7

• x = 6, -7

• x = 0

What is the first step in simplifying $\frac{1}{6x}-\frac{1}{x^2}$ ?

• Make the denominators of the rational expressions the same by finding the Least Common Denominator (LCD).

• Combine the numerators by the indicated operations (add and/or subtract) then copy the common denominator.

• Multiply the numerators together and the denominators together.

•  $\frac{x-6}{6x^2}$  

My first step will be to change the operator to multiplication and reciprocate the second fraction when...

• Adding
• Subtracting
• Multiplying
• Dividing
