V2 - 15 = -2v Solve the Quadratic. What are the 2 solutions?

v=-5 and v=3

Step-by-step explanation:

We are given that

We have to find  two solutions of quadratic equation.

Using addition property of equality

  (By using factorization method)

Substitute each factor equal to 0

and

and

Hence, two solutions of quadratic equation are

v=-5 and v=3

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
