Question

x^2+ 1 1x -1452 by quadratic formula​

Answer 1

Step-by-step explanation:

$\frac{- b \frac{ + }{ - } \sqrt{b ^{2} - 4ac }}{2a} \\ here \: a = 1 \\ b = + 11 \\ c = - 1452 \\ \ = > \frac{ - 11 \frac{ + }{ - } \sqrt{ {11}^{2} - 4 \times 1 \times - 1452 } }{2} \\ \frac{ - 11 \frac{ + }{ - } \sqrt{5929} }{2} \\ = > \frac{ - 11 \frac{ + }{ - }77 }{2} \\ = > \frac{ - 11 + 77}{2} \: \: or \frac{ - 11 - 77}{2} \\ = > \frac{66}{2} or \frac{ - 88}{2} \\ = > 33$
