" 4."quad (x+4)^(2)-(x-5)^(2)=9

Find the HCF of f(x)=33 (2x + 3)^(2) (3x-4)^(3) (4x-5)^(4) and g(x)= 22 (x+1) (2x + 3) (4x-5)^(2) (4x^(2)-9)

The value of x for which ](x^(2)-5x+4)/(x^(2)-9x+18)[=(x^(2)-5x+4)/(x^(2)-9x+18) is

Write the following in their standard form: 4x^(4)-5x^(7)+2x^(8)-x^(5)+x^(2)+9x

(9+4sqrt(5))^(x)+(9-4sqrt(5))^(x)=18, then find x^(2)-(1)/(x^(2))

If (9+4sqrt(5))^(x)+(9-4sqrt(5))^(x)=18 then the value of x^(2)-(1)/(x^(2))

Factorize each of the following expressions: x^(4)+x^(2)+1 (ii) x^(4)+5x^(2)+9

What is the HCF of 36(3x^(4)+5x^(3)-2x^(2)) , 9(6x^(3)+4x^(2)-2x),54(27 x^(4)-x) ?
