" 18."x^(2)-7x-30

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

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

Resolve (1)/(x^(2)-7x-18) into partical fractions.

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

Find the numerical difference of the roots of equation x^(2)-7x-18=0

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

30x^(2)+7x-15

When x approaches -oo , then what will be the tendency of the graph 5x^8+3x^7-18x^4-7x-30 ?
