Question

2. State whether the following equation is quadratic equation in x?

2xsq. + 5/2x-v3 = 0
​

Answer 1

Answer:

iv) (x – 3)(2x +1) = x(x + 5) (v) (2x – 1)(x – 3) = (x + 5)(x – 1) (vi) x2 + 3x + 1 = (x – 2)2 ... Thus, the required quadratic equation is: 2x2 + x – 528 = 0 ... If so, determine their present ages.
