Question

solve x2 + 2x + 5 = 0 by factorization method​

Answer 1

$\huge{\underline{\green{\bold{Answer}}}}$

= x² + 2x + 5 = 0

$x=\dfrac{-2±\sqrt{2^{2}-4\times 5}}{2}$

$x=\dfrac{-2±\sqrt{4-4\times 5}}{2}$

$x=\dfrac{-2±\sqrt{4-20}}{2}$

$x=\dfrac{-2±\sqrt{-16}}{2}$

$x=\dfrac{-2±4i}{2}$

$x=\dfrac{-2+4i}{2}$

$x=\dfrac{-2±4i}{2}$

x=−1+2i

x=−1−2i

Answer 2
