Question
\(x^{2}-250x-750000=0\)
Solution
Quadratic Formula Method
1
\( \text{Compare } x^{2} - 250 x - 750000 = 0 \text{ with the standard quadratic equation } ax^2 +bx+c = 0 \text{ and find the values of a, b, and c } \)
\( a = 1 \text{ , } b = -250 \text{ , } c = -750000 \)
2
Calculate the value of the discriminant (D)
\( D = 3062500 \)
3
Determine the nature of the roots
The roots are real and distinct
4
\( \text{ Apply the quadratic formula } \)
\(x = \frac{250 \pm 1750}{2}\)
5
\( \text{Find the roots of given quadratic equation } x^{2} - 250 x - 750000 = 0 \)
\( \text{The roots are } 1000 \text{ and } -750 \)
