Question

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

Answer 1

v=-5 and v=3

Explanation:

We are given that

`v^2-15=-2v`

We have to find two solutions of quadratic equation.

`v^2+2v-15=0`

Using addition property of equality

`v^2+5v-3v-15=0` (By using factorization method)

`v(v+5)-3(v+5)=0`

`(v+5)(v-3)=0`

Substitute each factor equal to 0

`v+5=0` and
`v-3=0`

`v=-5` and
`v=3`

Hence, two solutions of quadratic equation are

v=-5 and v=3
