Solving Rational Basics

Simplify

• A.
• B.
• C.
• D.

State the domain restrictions. 

• x ≠ -2
• x ≠ 2, 1
• x ≠ 2, -1
• x ≠ -2, 2, 1

What value(s) make the expression undefined?

• x = - 3 and x = 4
• x = 3 and x = - 4
• x = 3 only
• x = - 4 only

State the domain restrictions.

• x ≠ 3, -2, 6, -1
• x ≠ -1, 6
• x ≠ 3, -2
• No Domain Restrictions

Solve by cross-multiplying.

• x = -1, 5
• No Solution
• x = -4, 5
• x= -4

• There is no solution because the solution x = 6 is extraneous
• x = 6
• x = 7
• x = 5

Solve for x

• 4

• 2

• -2

• -4
