Re: Algebra Questions for SSC CGL
As you want I am here giving you Questions on Algebra topic for SSC CGL (Combined graduate level) examination. Sample question : If x , y are real and x2 + y2 + 2 = 2(y - x) then find the value of x Solution: here is only one equation so we have to solve the equation to get the value of x x2 + y2 + 2 = 2(y - x) x2 + y2 + 2 - 2y + 2x = 0 same variable put together, x2 + 2x + y2 - 2y + 2 = 0 x2 + 2x and y2 - 2y can make square if we add 1, x2 + 2x + y2 - 2y + 1 + 1 = 0 x2 + 2x + 1 + y2 - 2y + 1 = 0 or, (x + 1)2 + (y - 1)2 = 0 since sum of the square of the numbers never be zero unless all are zero therefore, x + 1 = 0 and y - 1 = 0 or, x = -1 Algebra questions for SSC CGL exam |
