Do­Now Begins! (Day 3)

Aim 7.4: How do we solve Regents style rational equation problems? HW: DeltaMath

• Incorrect LCM
• Ignored the denominator (m+1)
• Did not do check step
• Include (m+1) with the current LCM
• Make sure all denominators get eliminated or find new LCM
• Perform the check step

Do­Now Begins! (Day 2)

I don't get it!!!

Got part of it

I can do this!

Example 1

Steps to solve rational equations 1) Simplify the denominators (Factor, invert, or create them) 2) Find LCM of denominators 3) Multiply LCM to all numerators and eliminate like factors. Simplify and combine like terms. 4) Solve for variable and check for extraneous solutions (use factoring and/or quadratic solving techniques) Aim 7.4: How do we solve Regents style rational equation problems?

Classwork Time!

• Complete Classwork independently
• Check your answers with a partner.
• If you get stuck, raise your hand

silently.
