Find the value of vv that satisfies the equation v=5v+6v = \sqrt{5v + 6}. If there are multiple solutions, list them. If no solution exists, select "No solution".

STEP 1

Assumptions1. We are given the equation v=5v+6v=\sqrt{5v+6}. . We are asked to solve for vv.

STEP 2

To solve for vv, we first square both sides of the equation to eliminate the square root. This gives usv2=(5v+6)v^2 = (5v+6)

STEP 3

Rearrange the equation to set it equal to zero. This will allow us to use the quadratic formula to solve for vv.
v25v6=0v^2 -5v -6 =0

STEP 4

The quadratic formula is given byv=b±b24ac2av = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}where aa, bb, and cc are the coefficients of the quadratic equation ax2+bx+c=0ax^2 + bx + c =0.

STEP 5

In our equation, a=1a=1, b=5b=-5, and c=c=-. Substituting these values into the quadratic formula gives usv=(5)±(5)24(1)()2(1)v = \frac{-(-5) \pm \sqrt{(-5)^2 -4(1)(-)}}{2(1)}

STEP 6

implify the equation to getv=5±25+242v = \frac{5 \pm \sqrt{25 +24}}{2}

STEP 7

Further simplify the equation to getv=5±492v = \frac{5 \pm \sqrt{49}}{2}

STEP 8

implify the square root to getv=5±72v = \frac{5 \pm7}{2}

STEP 9

This gives us two possible solutions for vvv=5+72=6v = \frac{5 +7}{2} =6andv=572=v = \frac{5 -7}{2} = -

STEP 10

However, we must check these solutions in the original equation to make sure they are valid. Substituting v=6v=6 into the original equation gives us6=5(6)+6=36=66 = \sqrt{5(6) +6} = \sqrt{36} =6So v=6v=6 is a valid solution.

STEP 11

Substituting v=v=- into the original equation gives us=5()+6==- = \sqrt{5(-) +6} = \sqrt{} =This is not true, so v=v=- is not a valid solution.
The only solution to the equation v=5v+6v=\sqrt{5v+6} is v=6v=6.
