If a+b=17,and a – b =9, then the value of $$ {(4a^2+4b^2)}$$ is:

If x - y = 6 and xy = 40, then  find $$ {x^2+y^2}$$

If $$ {4p\over{{p^2}}-4p+4}={1\over8}$$, p≠0 then the value of $$ {p+{4\over p}}$$

If $$ {x+{1\over x}}=3$$ then find the value of $$ {x^2}-{1\over {x^2}}$$:

x-y=2, xy=24, then the value of (x²+y²) is:

If xy(x+y)=1, then $$ {1\over x^3 y^3}-{x^3-y^3}$$ is equal to-

$$ {a^2-b^2-2bc-c^2}\over{a^2+b^2+2ab-c^2}$$ is equal to

If (x+y+z)=12, xy+yz+zx=44 and xyz=48, then what is the value of x³+y³+z³=?
