Question

factorise----- 2x²+3√5x+5​

Answer 1

Answer:

$x = \frac{ - b + - \sqrt{ {b}^{2} - 4ac} }{2a} \\ \\ x = \frac{ - 3 \sqrt{5} + - \sqrt{45 - 40} }{4} \\ x = \frac{ - 3 \sqrt{5} + - \sqrt{5} }{4} \\ \\ \\ x = \frac{ - 3 \sqrt{5} + \sqrt{5} }{4} = \frac{ - \sqrt{5} }{2} \\ or \\ \\ \\ x = \frac{ - 3 \sqrt{5} - \sqrt{5} }{4} = - \sqrt{5}$
