Answer» let \'x\' be the numberThen,according to the questionx + x² = (63/4)4x²+ 4x -63 = 0Using splitting the middle term,4x² + 18x - 14x -63 = 02x(2x-9) - 7(2x-9) = 0(2x - 7)(2x - 9) = 0⇒ x = (7/2) or (9/2)x = (7/2) satisfy the condition given in the questionso, x =(7/2) is the number\xa0 Solve it like x +x^2=63/4 where x is the no. |
