Step-by-step explanation:
Answer:
(x + y - 2xy)*(x + y + 2xy)
Step-by-step explanation:
x^2-4x^2y^2+y^2+2*x*y
=x^2 + 2xy + y^2 - (2xy)^2
=(x + y)^2 - (2xy)^2
=(x + y - 2xy)*(x + y + 2xy)
Answer
Step-by-step explanation:
8^-5/8^-2
=8^5-(-2)
=8^5+2
=8^7
=2097152
Note in division if the base the base are same then u can subtract their exponent but in multiplication bases are same u should add their exponent.
Step-by-step explanation:
We have to make x the subject:
y = x² + 4x + 4.
=> y = (x + 2)² by completing the square
=> x + 2 = ±√y
=> x = ±√y - 2
Therefore the inverse is y = ±√x - 2.
