Answer:
4
Step-by-step explanation:
-3p+6+7p=22
-3p+7p=16
4p=16
p=4
To factor first multily 100 and 1 and get 100
then find what 2 numbers multiply to get 100 and add to get 20
the numbers are 10 and 10
so
split the center term up
100x^2+10x+10x+1
group
(100x^2+10x)+(10x+1)
undistribute
(10x)(10x+1)+(1)(10x+1)
undistribute/reverse distributive property
(10x+1)(10x+1)
(10x+1)^2
X+x²=30
x²+x-30=0
(x+6)(x-5)=0
x=-6 or x=5
