Question

2x2-7x +3=find the roots using quadratic formula ​

Answer 1

Answer:

$x = 3 \: or \: \frac{1}{2}$

Step-by-step explanation:

${2x}^{2} - 7x + 3 = 0$

a=2,b=-7,c=3

$x = - b + \frac{ \sqrt{ {b}^{2} - 4ac} }{2a}$

$x = 7 + \frac{ \sqrt{49 - 24} }{4}$

$x = 7 + \frac{ \sqrt{25} }{4}$

$x = 7 + \frac{5}{4}$

$x = \frac{7 + 5}{4}$

$x = \frac{12}{4} or \: \frac{2}{4}$

$x = 3 \: or \: \frac{1}{2}$
