X=5 because the factored form of the equation is (x-5)(x+3)=0 so if u set both of these equal to 0, then the other solution is 5.

Answer:

Other solution of the equation is x = 5

Step-by-step explanation:

Given Quadratic Equation,

x^2-2x-15=0

One of the solution of the given quadratic equation is x = -3

To find: 2nd solution of the equation.

We solve the given equation using middle term split method.

Consider,

x^2-2x-15=0

x^2-5x+3x-15=0

x ( x - 5 ) + 3 ( x - 5 ) = 0

( x - 5 )( x + 3 ) = 0

x - 5 = 0 ⇒ x = 5

x + 3 = 0 ⇒ x = -3

Therefore, Other solution of the equation is x = 5

Make a table of values for the following equation:
loris [4]

*Not 100% sure what you want but here goes*

Step-by-step explanation:

So what you do is create a table for this example label the x values say -2 through 2. Then you plug in the x value to the equation so for 2 its <u>y=</u><u> </u><u>2</u><u>(</u><u>2</u><u>)</u><u>+</u><u>5</u> which is 9. Continue this for the rest of the graph and that should do it.

Hope this helps

The first answer of the missing blank is 4/5.

The second answer of the missing blank is 2.

The third answer of the missing blank is 25.

*For all of these solutions, I will be using the common rules for logarithms.*

Solution for the first question:

Log9^4/5 must equal log9^4-log9^5, or it could also equal the more proper version, which is simplified: 2log9^2-log9^5.

Solution for the second question:

Log3^22 must equal log3^11+log3^2, if you break it down.

Solution for the third question:

Log9^25 must equal 2log9^5 because it will be like this when simplifying it:

log9^25=2log9^5

log9^5²=2log9^5

2log9^5=2log9^5

These are all of the step-by-step procedures for all three of these given questions. Anyways, I hope that this helped you!
