Can some one plz help

x = ±i, x = ±i

Step-by-step explanation:

x^4 + 3x^2 + 2 = 0

x^4 + x^2 + 2x^2 + 2 = 0

x^2 ( x^2 + 1 ) + 2 ( x^2 + 1 ) = 0

( x^2 + 2 ) ( x^2 + 1 ) = 0

x^2 + 2 = 0, x^2 + 1 = 0

x^2 = -2, x^2 = -1

x = ±i, x = ±i

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
