Question

If the roots of the Quadratic equation (a + b) x2 – 2 (ac + bd) x + c + d² = 0 are
equal. Prove that a by b is equal to c by d
​

Answer 1

• it's very simple because ac➕bd mean a=b by first same then c=d by second so next is
• x ➕c ➕d2 =0
• so here x adding to c then adding to d2 so main point is 1st one.
