Step-by-step explanation:
1. difference in algebraic expression is known SUBTRACTION
a² -b²=(a+b)(a-b)
see on "a" there is square and also on b
2. no there is no matter
now let multiply (a+b) (a-b)
a²+ab-ab-b²
a²-b²
now let multiply (a-b) (a+b)
a²+ab-ba-b²
ab and ba is same
a² -b²
Answer:
For this we need to solve using the transposition method
Step-by-step explanation:
We need to shift variables and constants from the RHS to LHS sgregating the x. + becomes - and x becomes /
The square root of 81 is 9, this can be proven by squaring 9, which's result is 81.
Answer:
(y-8)
Step-by-step explanation:
the other factor =
(y²-10y+16)/(y-2) =
(y-8) (y-2) /(y-2) =
eliminate (y-2),
we have (y-8)
