One of the solutions to x^2-2x-15=0 is x=-3. what is the other solution?

Other solution of the equation is x = 5

Step-by-step explanation:

Given Quadratic Equation,

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 ( 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

exa:

)

3+11

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
