Question

solve the equation using formula Y²+6y +5=0
pls i need it​

Answer 1

Answer:

${y}^{2} + 6y + 5 = 0 \\ \\ = > {y}^{2} + (5 + 1)y + 5 = 0 \\ \\ = {y}^{2} + 5y + y + 5 = 0 \\ \\ = > y(y + 5) + 1(y + 5) = 0 \\ \\ = > (y + 5)(y + 1) = 0 \\ \\ either \: y + 5 = 0 \\ \\ = > y = - 5 \\ \\ or \: y + 1 = 0 \\ \\ = > y = - 1$

Answer 2

$\large{\bold{\huge{\overbrace{\underbrace{ANSWER:}}}}}$

y²+6y+5 = 0

y² + 5y + y + 5 = 0 (splitting middle term)

y(y+5)+1(y+5)=0

(y+1)(y+5)=0

so,

y+1 = 0

y = -1

or

y+5 = 0

y = -5

therefore, y = -1; y = -5
