Question

factorize x2 + 6x + 4

Answer 1

Answer:

By applying quadratic formula,

x = (-6+√36-4×1×4)/2

x = (-6+√20)/2

x =( -6+2√5)/2

x = -3+√5

x = -3+√5 or x = -3-√5

Answer 2

Answer:

-3 ± √5

Step-by-step explanation:

{-b ± √(b²-4ac)}/2a

-6/2 ±√(36-16)/2

= -3 ± √5

for further, √5 is appx 2.236 (mug it up)

x= -5.236, + 0.764 appx
