Answer:
For extracting square roots the examples are:
1.) x²=25
2.) x²+16
For factoring the examples are:
1.) x²+7x=0
2.) x²+5x-14=0
those are the basics examples you will encounter more the hardest one.
Step-by-step explanation:
Solutions for extracting square roots:
1.) x²=25
square root the left and right sides
√x²=√25
x=5
2.)x²+16
you need to change first the equation like this
x²=16
then square the both sides
√x²+√16
x=4
Solutions by factoring:
1.)x²+7x=0
x(x+7)=0
x= -7
2.)x²+5x-14=0
(x-2)(x+7)=0
x=2, x= -7
