Factor Y4_+y2_-12 need factor of this equation

y = ±√3 and ±2i

Step-by-step explanation:

Given the equation y⁴+y²-12 = 0

(y²)²+y²-12 = 0

Let P = y²

Substitute

P²+P-12 = 0

Factorize:

P²+4P-3P -12 = 0

P(P+4)-3(P+4) = 0

(P-3)(P+4) = 0

P-3 = 0 and P+4 = 0

P = 3 and -4

When P = 3

y² = 3

y = ±√3

When P = -4

y² = -4

y² = ±√-4

y = ±2i

Hence the value of y is ±√3 and ±2i

step-by-step explanation:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
