Question

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

Answer 1

Answer:

v=-5 and v=3

Step-by-step 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
