Question

solve quadratic equation by factorization method: x²+8x+15=0

x=5,x=3
x=-5,x=-3

Answer 1

$\Large{\underline{\underline{\blue{\bold{✄Solution:}}}}}$

$→\;{\sf{x²+8x+15 = 0}}$

$→\;{\sf{x²+3x+5x+15 = 0}}$

$→\;{\sf{x(x+3)+5(x+3) = 0}}$

$→\;{\sf{(x+3)(x+5) = 0}}$

$→\;\red{\bold{x = -3 \;\; \& \;\;x = -5}}$
