Solve the equation by factoring. Simplify all irrational and complex solutions.

see below

Step-by-step explanation:

Let's solve your equation step-by-step.

x4−16x2=x2+18

Step 1: Subtract x^2+18 from both sides.

x4−16x2−(x2+18)=x2+18−(x2+18)

x4−17x2−18=0

Step 2: Factor left side of equation.

(x2+1)(x2−18)=0

Step 3: Set factors equal to 0.

x2+1=0 or x2−18=0

x=4.242640687119285 or x=−4.242640687119285

x=4.242640687119285 or x=−4.242640687119285

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
