Use the quadratic formula to find the solutions to the equation.<br> 3x2 - 10x + 5 = 0

Nitella [24]

Answer: A

Step-by-step explanation:

3x² - 10x + 5 = 0

a = 3 b = -10 c = 5

Δ = b²- 4ac = 100 - 4.3.5 = 40 > 0 => have 2 solutions

=> x = $\frac{10+\sqrt{40} }{6}$ or x = $\frac{10-\sqrt{40} }{6}$
