Question

solve the following by quadratic formula

$x {}^{2} + 5x - 750$

Answer 1

The answer is 25 and-30

Answer 2

${x}^{2} + 5x - 750$
B=5 ; A=1 ; C=-750


B^2 -4AC
25 + 3000
3025...


$x = \frac{ - b( + - ) \sqrt{ {b}^{2} - 4ac} }{2a}$
$x = \frac{ - 5( + - ) \sqrt{3025} }{2}$
$x = \frac{ - 5 + 55}{2} .... \frac{ - 5 - 55}{2}$

$x = \frac{50}{2} .... - \frac{60}{2}$
$x = 25..... - 30$
