Question

Solve the equation 2x2

-7x+3=0 by using general formula.​

Answer 1

refer to the image complete answer is given

Answer 2

Step-by-step explanation:

Given, 2x2 -7x+3=0

On comparing it with ax 2+bx+c=0 where a=2,b=-7 and c=3

∴ b ^2−4ac=(-7) ^2 −4×2×3

49−24=25

$x=−b± \sqrt{b^{2} −4ac} \2a </p><p></p><p>$

$= - ( - 7)± \sqrt[]{( - 7) {}^{2} } - 4(2)(3) \2 \times 2$

=7± √49-24
