Question

Find the roots of following quadratic equation by the method of completing the square
$2x ^{2} - 7x + 3 = 0$
​

Answer 1

this is answer of

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

Answer 2

Answer:

x=3       x=  1/2

Step-by-step explanation:

2x2−7x+3=0

⇒x2−7/2x= −3/2

Adding (7/4)^2 on both sides

⇒x2−7/2x+(7/42=-3/2+(7/4)2

⇒(x−7/4)2=-3/2+49/16

⇒(x−7/4)2=25/16

⇒(x−7/4)2=(5/4)2

Taking square root on both sides

⇒(x−7/4)=±5/4

X=5/4+7/4    x=-5/4+7/4

X=3                        x=1/2
