Answer:

x = −2 or x = 4.23606797749979 or x = −0.2360679774997898

Step-by-step explanation:

Subtract x^3-2x^2-9x-2 from both sides.

0 − (x3−2x2−9x−2) = x3−2x2−9x−2 − (x3−2x2−9x−2)

−x3+2x2+9x+2=0

Factor left side of equation.

(−x−2)(x2−4x−1)=0

Set factors equal to 0.

−x−2=0 or x2−4x−1=0

umka2103 [35]

using pythagorean theorem

a^2 + b^2 = c^2

(12x)^2 + (16x)^2 = 10^2

square each term

144x^2 + 256x^2 = 100

combine like terms

400 x^2 = 100


divide by 400 on each side

x^2 = 1/4

take the square root on each side

x = 1/2
