Answer:

  • -11/5 or -1/4

Explanation:

There are two possibilities in this question.

________________________________________________

Possibility No. 1

Given:

  • b/2a + b
  • b = -2
  • a = 5

Step-1: Substitute the values given into the equation.

  • b/2a + b
  • => -2/2(5) + (-2)

Step-2: Solve.

  • => -2/10 - 2
  • => -1/5 - 2
  • => -11/5

Hence, the solution for possibility No. 1 is -11/5.

________________________________________________

Possibility No. 2

Given:

  • b/2a + b
  • b = -2
  • a = 5

Step-1: Substitute the values given into the equation.

  • b/2a+b
  • => -2/2(5)+(-2)
  • => -2/10 - 2
  • => -2/8
  • => -1/4

Hence, the solution for possibility No. 2 is -1/4.
