Answer 1

SOLUTION :-

=>(1) 2x² - 7x + 3 = 0

=>On comparing this equation with ax²+bx+c=0 ,we obtain

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

=>By using quadratic formula, we obtain,

$=> \sf{ x = \frac{ - b± \sqrt{b { }^{2} - ac} }{2a} } \\=> \sf{x = \frac{7± \sqrt{49 - 24} }{4} } \\=> \sf{x = \frac{7± \sqrt{25} }{4} } \\ => \sf{x = \frac{7± 5 }{4} } \\ => \sf{x = \frac{7 + 5}{4} } \: \: or \: \: x = \frac{7 - 5}{4} \\ \ => \sf{x = \frac{12}{4} \: \: or \: \: \frac{2}{4} }\\ => \sf \red{x =3 \: \: or \: \: \frac{1}{2} }$
