Question

3x²- 5x+2=0. by quadratic formula.​

Answer 1

Answer:

X = 1 or X = 2/3

Step-by-step explanation:

${3x}^{2} - 5x + 2 \\ a = 3 \: \: b = - 5 \: \: c = 2\\ x = \frac{- b \: ± \: \sqrt{ {b}^{2} - 4ac} }{2a} \\ x = \frac{ - ( - 5)± \sqrt{ { (- 5)}^{2} - 4 \times 3 \times 2} }{2 \times 3} \\ x = \frac{5 \: ± \sqrt{25- 24} }{6} \\ x = \frac{5± \: \sqrt{1} }{6} \\ x = \frac{5 \:±1}{6} \\ x = \frac{5 + 1}{6} \: \: or \: \: x = \frac{5 - 1}{6} \\ x = \frac{6}{6} \: \: or \: \: x = \frac{4}{6} \\ x = 1 \: \: \: or \: \: x = \frac{2}{3}$
