Question

find the roots of x²+49=0 find it​

Answer 1

${x}^{2} + 49 = 0$

$= {x}^{2} = - 49$

$= x = \sqrt{ - 49}$

$= x = - 7$

Answer 2

Answer:

${x}^{2} + 49 = 0 \\ \\ 49 = - {x}^{2} \\ \\ - x = \sqrt{49} \\ \\ - x = 7 \: \: or \: \: - x = - 7 \\ \\ roots \: \: are \\ \\ x = - 7 \: \: and \: \: x = 7$
