If 2 is a root of the equation ax ² + ax + 2 = 0& x²-x-b=0 then find the value of a/b |
|
Answer» Answer: GIVEN quadratic equations x 2 −cx+d=0 ....(1) Let α,β be the roots of equation (1) x 2 −ax+b=0 .....(2) Let α,α be the roots of equation (2) 2α=a α= 2 a
Also , α 2 =b Since, α is a ROOT of (1), α 2 −cα+d=0 b+d= 2 ac
⇒2(b+d)=ac |
