Question

7. Find the roots of the equation x2 +6x+8 =0
​

Answer 1

Answer:

X = -2, -4

Step-by-step explanation:

x2 +6x+8 =0

(x+2)(x+4)=0

Answer 2

$= > {x}^{2} + 6x + 8 = 0 \\ = > x { }^{2} + (4 + 2)x + 8 = 0 \\ = > {x}^{2} + 4x + 2x + 8 = 0 \\ = > x(x + 4) + 2(x + 4 )= 0\\ = > (x + 2)(x + 4) = 0$

So rotts =-2,-4.
