Step 1: Trying to factor as a Difference of Squares:
Factoring: x²⁰⁰² - 1
Theory : A difference of two perfect squares, A² - B² can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A² - AB + BA - B² =
A² - AB + AB - B²
A² - B²
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 1 is the square of 1
Check: x²⁰⁰² is the square of x¹⁰⁰¹
Factorization is : (x¹⁰⁰¹ + 1) × (x¹⁰⁰¹ - 1)
Answer:
d
Step-by-step explanalime boba no other
Yes, i am what do you need help with?
4)
variables d and w
5d +1(4d)=36
9d=36
d=4 w=4x4=16
difference of price $12
5)
E 5 comics
F= 10
G=20
e+ (e+5) + 2(e+5)=35
e+ e+5 + 2e +10 =35
4e +15=35
4e=20
e=5
Eugene = 5 comics
6)
Agnes and Billy had each 300 (after drinking it will be less water)
A 300-200 =100
B 300-100 =200
