What are the solutions of the equation x4 – 5x2 – 36 = 0? use factoring to solve. x = ±2 and x = ±3 x = ±2i and x = ±3 x = ±2 and x = ±3i x = ±2i and x = ±3i

x=3,-3,2i,-2i

Step-by-step explanation:

Given is a poynomial of degree 4 as

This polynomial has no terms with odd powers of x.

Hence for simplicity let us assume that

The equation becomes now a quadratic in y as

Equate each factor to 0 to get

Replace y by x square to have

Take square roots

are the solutions

i am sorry it just submitted an answer but the answer is 365 boys. hopes this

step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
