Rearrange the polynomial:
a^2–2ab+b^2 - c^2
((a-b)(a-b))-c^2
(a-b)^2-c^2
Set x =a-b and y=c. The formula becomes
x^2-y^2
factoring this polynomial, we get
(x+y)(x-y)
Substituting back, we get:
(a+b+c)(a+b-c)
Let’s multiply it out to check:
A^2 -ab ac
- ab B^2 -bc
-ac bc -c^2
Step-by-step explanation:

13:8</h3><h3>
A=13x. B=8x</h3><h3>
13x + 8x = 44</h3><h3>
21x=44</h3><h3>
x=2.095</h3>

Log(1/216)^(x+2) = log 6^12
(x+2) log(1/216) = log 6^12
xlog(1/216) + 2log(1/216) = log6^12
xlog(1/216) = log6^12 - 2log(1/216)
x = [log6^12-2log(1/216] / log(1/216)
x = -6
