SOLUTION
2x² - 7x +3=0
On comparing this equation with ax² +
bx + c = 0, we get
a = 2, b = -7 and c = 3
By using quadratic formula, we get
x = -b+sqrt(b2-4ac)/(2a)
⇒ x = 7+sqrt(49-24)/4
⇒ x = 7+sqrt25/4
⇒ x = 7±5/4`
= (7+5)/4 View in app X
⇒ x = 12/4" or " 2/4
"..x = 3" or " 1/2"

Answer:
solution:-
Given equation is 2x2−7x+3=0
Hence, a=2,b=−7,c=3
Therefore, x=2a−b±b2−4ac
=47±25
=47±5
Thus, x=3 and x=21
