Answer:
Yes
Step-by-step explanation:
(x-1)(x+1)(x-3i)(x+3i)
FOIL ( x-1) (x+1) = x^2 -x+x-1 = x^2 -1
FOIL (x-3i)(x+3i) = x^2 +3ix -3ix -9i^2 = x^2 -9(-1) = x^2 +9
(x-1)(x+1)(x-3i)(x+3i) = (x^2 -1) (x^2 +9)
FOIL again
x^4 +9x^2 -x^2 -9
x^2 +8x^2 -9
This is the factored form
Answer:
y = 1
Step-by-step explanation:
Simplifying
8y + -3 = 5
Reorder the terms:
-3 + 8y = 5
Solving
-3 + 8y = 5
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + 8y = 5 + 3
Combine like terms: -3 + 3 = 0
0 + 8y = 5 + 3
8y = 5 + 3
Combine like terms: 5 + 3 = 8
8y = 8
Divide each side by '8'.
y = 1
Simplifying
y = 1
i don't know if it right
