Answer:
Given: x²5x - 10 = 0
On comparing the given equation with ax² + bx + c = 0, we get: a = 1, b = -5 and c = -10
For ax²+bx+c = 0, we know that,
-b ± √b² - 4ac 2a X =
[Quadratic
formula]
5± √(-5)² - 4 × 1 × (-10) ... X = 5± √65 2
2 x 1
5 ± 8.06 2
5 +8.06 5-8.06 2 2
13.06 3.06 2 2
Hence, x = 6.53, or x = -1.53.
