Question

Solution set of equation √1x²5x+la
1​

Answer 1

First, simplify the equation so the absolute value is all that remains on the left side of the equation:

|2x – 25| = 10

Now create two equalities, one for 10 and one for –10.

2x – 25 = 10 and 2x – 25 = –10

2x = 35 and 2x = 15

x = 17.5 and x = 7.5

The two solutions are 7.5 and 17.5. 17.5 + 7.5 = 25
