Step 1

Step 2

Step 3

Where, if at all, did Theo first make a mistake finding the measure of x?

step 1

step 2

step 3

Theo did not make a mistake.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
