" (2) "x^(2)-7x=30

If x ^(2) -7x =30 and x gt0, what is the value of x -5 ?

Factorise: x ^(2) - 7x- 30

sqrt(3x^(2)-7x-30)-sqrt(2x^(2)-7x-5)=x-5

If sqrt(3x^(2)-7x -30) - sqrt(2x^(2) -7x -5) = x -5 has alpha and beta as its roots, then the value of alpha beta is

If the roots of (x^(2)-7x-30)=0 and (x^(2)-3x+4=0) are alpha,beta and alpha+beta,beta+k respectively then k=?

Find all zeros of the polynomial 2x^(4)+7x^(3)-19x^(2)-14x+30, if two of its zeros are sqrt(2) and -sqrt(2) .

One of the factors of the expression (2x-3y)^(2)-7(2x-3y)-30 is
