One root of the quadratic equation (2x-3) (x+5)=0 is -5, then the other root is |
|
Answer» Alpha = -5 , Beta (2x-3) (x+5) = 0 2x2+10x-3x-15 = 0 2x2+7x-15 = 0 Therefore, a = 2, b = 7, c = -15 We know that, Alpha * Beta = c/a -5 * Beta = -15/2 Beta = -15/2*-5 Beta = -15/-10 i.e Beta = 15/10 Therefore, Beta = 1.5 or 3/2 |
