From above, then we let b, -a are root of a quadric equation s.t. -ab=-10, b+(-a)=3 ie, equation is x^2-3x-10=0 (x+2)(x-5)=0 then (a=2,b=5) or (a=5,b=2) by putting to original equation, answer is found

Attempt: There's an error in your first line. You have "FOI" but not "L"! so this should be You have ab- 3= 7 and b- a= 3 => => => => => => ... Ans.: (From text book): a = 2, b = 5 a= -5, b= -2 is also a solution.
Great. Thanks guys.
