Math 10 Chapter 9 - Part C


1. From standard quadratic equations, variable is eliminated by cross multiplication method.


2. A variable may be eliminated by comparison or by substitution method.


3. If x/a + a/x = m and x3/a3 + a3/x3 = n, then relation free from x is m3 =n


4. If y = 2x and y = 2m then eliminant free from y is 2x = m


5. If y = 2/t and y = 1/2s then relation free from y is 4s = t


6. Eliminating 'm' from m2 + 1/m2 =x2 and m + 1/m = y we get x2 | y2 = 2


7. Eliminating 'm' from m | z = 2 and m + y = 5 we get z + y = 3


8. Eliminating 'x' from 1/x= 3m and x = 1/3n we get m = n


9. Eliminating t from y = 3t and yt = 1, we get




10. Eliminating t from x+t =2p and y | t = 4q




11. The relation free from 'x' for equations x = 1/3n, x= m is




12. Eliminating 'm' for equations m + x = 3c and m | y = 3d, we get




13. Eliminating 'm' from m3 = 4t and m = n/4




14. Eliminating 'z' from x-z = 3 and y + z = 5




15. From equations ax2 + bx + c = 0 and lx2 + mx + n = 0 'x' can be eliminated by the method of




16. If x + 1/x = a + b and x | 1/x = a-b eliminant is




17. Eliminating x from x = a, 1/x = bwe get




18. The relation free of t from the equations a + t = 3 and b | t = 5




19. If x = 2m and y = 8m then a relation free from 'm' is




20. If z = 7 and z + x = 9 then a relation independent of z is
