Question

(b) (2x^4 – x^2 - 36) = (2x^2 - 9)=? ​

Answer 1

The answer is 51 centimetres.

Answer 2

Answer:

2x4-x2-36=0 

Four solutions were found :

  x=  0.0000 - 2.0000 i 

  x=  0.0000 + 2.0000 i 

 x = ±√ 4.500 = ± 2.12132

Step by step solution :

Step  1  :

Equation at the end of step  1  :

(2x4 - x2) - 36 = 0
