Question

Find the roots of quadratic equation 5 x square-6 x - 2 = 0

Answer 1

Step-by-step explanation:

5x^2 - 6x - 2 = 0

here, b = -6, a = +5, c = -2

lets apply the quadratic formula,i.e.

[-b ± (√b^2 - 4ac)] / 2a

so, {-(-6) ± [√(-6)^2 - 4(5)(-2)]} / 2(5)

[+6 ± √(36 + 40)] /10

(+6 ± √106) / 10

So, x = (6 + √106) / 10 and x = (6 - √106) / 10
