Solve the following quadratic equation for x. X square - 4ax - b square +4a square = 0 |
| Answer» We have,x2 - 4ax + 4a2 - b2\xa0= 0{tex}\\Rightarrow{/tex}(x -2a)2\xa0- b\u200b\u200b\u200b\u200b\u200b\u200b2\xa0= 0{tex}\\Rightarrow{/tex}(x - 2a + b)(x- 2a- b) = 0{tex}\\Rightarrow{/tex}x -2a + b = 0 and x -2a - b = 0{tex}{/tex}{tex}\\Rightarrow{/tex}\xa0x = 2a - b or 2a + b | |
