Answer:

  (a)  y = (-6 +2√6)/5  and  y = (-6 -2√6)/5

Step-by-step explanation:

You want the solutions to the quadratic (5y +6)² = 24.

Solution

Take the square root of both sides:

  5y +6 = ±2√6

  5y = -6 ±2√6 . . . . . . subtract 6

  y = (-6 ±2√6)/5 . . . . divide by 5

The solutions are ...

  • y = (-6 +2√6)/5
  • y = (-6 -2√6)/5
