Question

1. Find the roots of the following quadratic equations, if they exist
i ) 2x​

Answer 1

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

${x}^{2} - \frac{ - 7}{2} = \frac{ - 3}{2}$

$adding \: \frac{ {7} }{4}^{2} on \: both \: sides$

${x}^{2} \frac{ - 7}{2}x - ( \frac{7}{4})^{2}$

Answer 2

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

${x}^{2} - \frac{ - 7}{2} = \frac{ - 3}{2}$

$adding \: \frac{ {7} }{4}^{2} on \: both \: sides$

${x}^{2} \frac{ - 7}{2}x - ( \frac{7}{4})^{2}$
