Solve for x
#23
x^2+10x-75=0
(x-5)(x+15)
x= -5 or x= -15

In order to solve this you must find out how many x's are in the equation thus giving you (x )(x )
then you have to find out what two numbers added together equals 10, but at the same time when multiplied together equals -75.
once you find that out your final product should look like this (x-5)(x+15)
If you want to solve for x you have to find a number when multiplied by the numbers you found equals 0




Factoring:

ex #1:
xˆ2-13x+12
Solution:
(x-12) (x-1)

ex #2:
xˆ2-3x-40
Solution:
(x-8) (x+5)

ex #3:
xˆ2-10x+24
Solution:
(x-6) (x-4)
