Question

if (ax^2+c)y+(a'x^2+c')=0 and x is a rational function of y& ac is negative then ​

Answer 1

Answer:

if (x+a) is a factor then p(a)=0.

p(a)=(-a)^2n-a^2n

= -an-an = 0.

therefore (x+a) is a factor of p(x).

Hope it helps..

Answer 2

Answer:

Step-by-step explanation:

x*5/2+2/3=-7/12,

5x/2+2/3=-7/2,

denominators L.C.M=6

5x/2*6+2/3*6 total /6,

15x+4= -7/2,

30x+8=-7,

30x=-15,

x=-15/30,

x=-1/2.

hence the rational number should be =-1/2
