Question

2xsquare+13x+1=0 solved the equation​

Answer 1

Answer:

$2 {x}^{2} + 13x + 1 = 0 \\multiply \: by2 \\ 4 {x}^{2} + 26x + 2 = 0 \\ {2x}^{2} + 2 \times 2x \times \frac{13}{2} = - 2 \\ {2x}^{2} + 2 \times 2x \times \frac{13}{2} + { (\frac{13}{2} )}^{2} = - 2 + {( \frac{13}{2}) }^{2} \\ {(2x - \frac{13}{2} )}^{2} = \frac{165}{2} \\ 2x - \frac{13}{2} = \sqrt{ \frac{165}{2} }$
