The roots of an equation are x = -1 ± i. The equation is x2 +__ + 2 = 0.

Karolina [17]

[x-(-1+i)][x-(-1-i)]
[(x+1)-i][(x+1)+i]
(x+1)²-i²
(x²+2x+1)+1
x²+2x+2
so the answer is 2x

Select all the expressions that represent a correct solution to the equation 6(×+4)=20

kozerog [31]

Answer:

the solution $x = \frac{-2}{3}$

Step-by-step explanation:

Given equation is 6 ( x+4) =20

<u>Distributive property</u>:-

a .(b + c) = a .b + a . c

Given equation is 6 ( x+4) =20

by using distributive property 6 .x + 6.4 =20

6x +24 =20

subtracting '24' on both sides, we get

6x +24 -24 = 20 -24

6x = -4

dividing by '6' on both sides, we get

$\frac{6x}{6} = \frac{-4}{6}$

$x = \frac{-4}{6}$

<u>Final answer</u> :-

the solution of given equation is $x = \frac{-2}{3}$
