Question

x^2- 50x-525=0 Find value of X ​

Answer 1

Answer :-

$\rm x^2 - 50x - 525 = 0$

By using quadratic formula :-

$\rm x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac } }{2a}$

$\rm x = \frac{ - (- 50) + \sqrt{ {50}^{2} - 4(1)(525) } }{2 \times 1}$

$\rm x = \frac{50 \pm \sqrt{400} }{2}$

$\rm x = \frac{50 + 20}{2} , \frac{50 - 20}{2}$

$\rm x = \frac{70}{2} , \frac{30}{2}$

$\rm x = 35 , 15$
