Answer : - 1-root 24 and - 1+root 24
[tex] {x}^{2} + 2x - 5 \\ solving \: by \: quadratic \: formula - \\ a = 1 \: \: b = 2 \: and \: c = ( - 5) \\ - b \ \sqrt{{b}^{2} - 4ac} \div 2a \\hey \: mate \: do \: add \: a + and \: - sign \: before \: the \: root \: \\ so \: putting \: the \: values \\ - 2 \sqrt{4 - 4( - 5) } \div 2 \\ - 2 \sqrt{24} \div 2 \\ so \: your \: answer \: is \: \\ - 1 + \sqrt{24} \: and \: - 1 - \sqrt{24} [tex]
