Question

Y=x^2+5×+2 y=×-1pls​

Answer 1

Answer:

$x=-1 \ or \ x=-3$

Step-by-step explanation:

$y = x^2 + 5x +2\\y = x-1$

Equating both equations equal to each other:

$x^2 + 5x+2 = x-1\\x^2+5x+2 -x +1 =0\\x^2 + 4x +3 = 0$

Breaking the middle term:

$x^2 + 4x +3 =0\\x^2 +3x + x +3 =0 \\x(x+3) +1 (x+3) = 0\\(x+1)(x+3)=0\\x+1 =0 \ or \ x+3 =0\\x=-1 \ or \ x=-3$
