Answer:
a2 – b2 = (a – b)(a + b)
(a + b)2 = a2 + 2ab + b
a2 + b2 = (a + b)2 – 2ab
(a – b)2 = a2 – 2ab + b

Answer:
Step-by-step explanation:
x^2/100 + y^2/25=1 -----(1)
Since 25<100
Hence the above equation is of the form x^2/a^2+ y^2/b^2=1-------(2)
Comparing (1) and (2)
a^2=100
a=10
Major axis=2a=20
