The answer is D one trillion percent
N^4 - 1 = (n^2 - 1)(n^2 + 1)
= (n + 1)(n - 1)(n^2 + 1)
Answer:
lets take a differential equation
taking derivative of M w.r.t y and N w.r.t x
so this is an in exact equation we will find integrating factor and make it exact equation
so 1/y is our integrating factor multiply it by the equation we will get an exact equation:
take derivative
now solving this exact equation
Answer:
see below
Step-by-step explanation:
4x - 4(30-2x)=24
4x-120+8x=24
12x=144
X=12
then substitute
2(12) + y =30
y=30-24
y=6
