Question

Solve the equation in x = 5. Round the answer to 4
decimal places.

Answer 1

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.
