If `sqrt (1+(49)/(576))=1+x/(24)`, then the value of x is |
|
Answer» `1 + 49/576 = (1 + x/24)^2` `1+ 49/576 = 1 + x^2/576 + 2x/24` `49/24 = x^2/24 + 2x` `49/24 = (x^2 + 48x)/24` `x^2 + 48x - 49 = 0` `x^2 + 49x - x - 49= 0` `(x+49)(x-1) = 0` `x=-49, 1` `x=-49` cannot be possible so,`x=1` option A is correct |
